This word might with great propriety he used, though the case was mostly preternatural; as the evil spirit would undoubtedly take advantage of the influence which the changes of the moon have on the brain and nerves.

Our Lord speaks principally this to his disciples.

Because in this particular they had not faith.

That is, the least measure of it. But it is certain, the faith which is here spoken of does not always imply saving faith. Many have had it who thereby cast out devils, and yet will at last have their portion with them. It is only a supernatural persuasion given a man, that God will work thus by him at that hour. Now, though I have all this faith so as to remove mountains, yet if I have not the faith which worketh by love, I am nothing. To remove mountains was a proverbial phrase among the Jews, and is still retained in their writings, to express a thing which is very difficult, and to appearance impossible. Mat 21:21; Luk 17:6.

Wesley: Mat 17:21 - -- goeth not out but by prayer and fasting - What a testimony is here of the efficacy of fasting, when added to fervent prayer! Some kinds of devils the ...
goeth not out but by prayer and fasting - What a testimony is here of the efficacy of fasting, when added to fervent prayer! Some kinds of devils the apostles had cast out before this, without fasting.

Mark (Mar 9:30), as usual, is very precise here: "And they departed thence"--that is, from the scene of the last miracle--"and passed through Galilee; and He would not that any man should know it." So this was not a preaching, but a private, journey through Galilee. Indeed, His public ministry in Galilee was now all but concluded. Though He sent out the Seventy after this to preach and heal, He Himself was little more in public there, and He was soon to bid it a final adieu. Till this hour arrived, He was chiefly occupied with the Twelve, preparing them for the coming events.

JFB: Mat 17:22 - -- Though the shock would not be so great as at the first announcement (Mat 16:21-22), their "sorrow" would not be the less, but probably the greater, th...
Though the shock would not be so great as at the first announcement (Mat 16:21-22), their "sorrow" would not be the less, but probably the greater, the deeper the intelligence went down into their hearts, and a new wave dashing upon them by this repetition of the heavy tidings. Accordingly, Luke (Luk 9:43-44), connecting it with the scene of the miracle just recorded, and the teaching which arose out of it--or possibly with all His recent teaching--says our Lord forewarned the Twelve that they would soon stand in need of all that teaching: "But while they wondered every one at all things which Jesus did, He said unto His disciples, Let these sayings sink down into your ears; for the Son of man shall be delivered," &c.: "Be not carried off your feet by the grandeur you have lately seen in Me, but remember what I have told you, and now tell you again, that that Sun in whose beams ye now rejoice is soon to set in midnight gloom." Remarkable is the antithesis in those words of our Lord preserved in all the three narratives--"The son of man shall be betrayed into the hands of men." Luke adds (Luk 9:45) that "they understood not this saying, and it was hid from them, that they perceived it not"--for the plainest statements, when they encounter long-continued and obstinate prejudices, are seen through a distorting and dulling medium--"and were afraid to ask Him"; deterred partly by the air of lofty sadness with which doubtless these sayings were uttered, and on which they would be reluctant to break in, and partly by the fear of laying themselves open to rebuke for their shallowness and timidity. How artless is all this!

When they were come to the multitude - It appears that a congregation had been collected during our Lord’ s stay on the mount: how great must have been the desire of these people to hear the words of Christ! The assembly is self-collected, and no delay on the preacher’ s side discourages them - they continue to wait for him. In the present day how rare is this zeal! How few by the most pathetic invitation can be brought together, even at the most convenient times, to hear the same doctrines, and to get their souls healed by the same wonder-working Christ

Falleth ofttimes into the fire, and oft into the water - The paroxysms of his disorder frequently recurred; and among his numerous falls, some were into the fire and some into the water: so that, on this account, his life was in continual danger. Those who are under the influence of the devil are often driven to extremes in every thing. Such are often driven into the fire of presumption, or the waters of despair. Satan takes advantage of our natural temper, state of health, and outward circumstances, to plague and ruin our souls.

Thy disciples could not cure him - No wonder, when the cure must be effected by supernatural agency, and they had not faith enough to interest the power of God in their behalf, Mat 17:20. A spiritual disorder must have a spiritual remedy: natural means, in such cases, signify just - nothing.

This last expression could not have been addressed to the disciples, who were certainly saved from the corruption of the world, and whose minds had been lately divinely illuminated by what passed at and after the transfiguration: but at all times the expression was applicable to the Jewish people.

There are some souls whose cure God reserves to himself alone, and to whom all the applications of his ministers appear to be utterly ineffectual. He sometimes does all without them, that they may know they can never do any good without him. Quesnel.

Why could not we cast him out? - They were confounded at their want of success - but not at their want of faith, which was the cause of their miscarriage! When the ministers of the Gospel find their endeavors, with respect to some places or persons, ineffectual, they should come, by private prayer, to Christ, humble themselves before him, and beg to be informed whether some evil in themselves have not been the cause of the unfruitfulness of their labors.

Because of your unbelief - Are we preachers of the Gospel? Do the things of God rest upon our minds with a deep and steady conviction? Can we expect that a doctrine which we do not, from conviction, credit ourselves, can be instrumental in our hands of begetting faith in others? So we preached, end so ye believed. The word preached generally begets in the people the same spirit which the preacher possesses. Instead of

As a grain of mustard seed - Some eminent critics think this a proverbial expression, intimating a Great Degree of faith, because removing mountains, which St. Paul, 1Co 13:2, attributes to All Faith; i.e. the greatest possible degree of faith, is attributed here, by our Lord, to that faith which is as a grain of mustard seed. However this may be, there can be no doubt that our Lord means, as Bishop Pearce well remarks, a thriving and increasing faith; which like the grain of mustard seed, from being the least of seeds, becomes the greatest of all herbs; even a tree in whose branches the fowls of the air take shelter. See Wakefield’ s Comment, and the note on Mat 13:32 (note).

They were exceeding sorry - Since the conversation on the mount, with Moses and Elijah; Peter, James, and John could have no doubt that their Lord and Master must suffer, and that it was for this end he came into the world; but, while they submitted to the counsel of God, their affection for him caused them to feel exquisite distress.

Mat 17:17.O unbelieving and rebellious nation Though Christ appears to direct his discourse to the father of the lunatic, yet there can be no doubt that he refers to the scribes, as I have lately explained; for it is certain that the reproof is directed, not against ignorant and weak persons, but against those who, through inveterate malice, obstinately resist God. This is the reason why Christ declares that they are no longer worthy to be endured, and threatens that ere long he will separate from them. But nothing worse could happen to them than that Christ should leave them, and it was no light reproach that they rejected so disdainfully the grace of their visitation. We must also observe here, that we ought to treat men in various ways, each according to his natural disposition. For, while our Lord attracts to him the teachable by the utmost mildness, supports the weak, and gently arouses even the sluggish, he does not spare those crooked serpents, on whom he perceives that no remedies can effect a cure.

Mat 17:19.Then the disciples coming The disciples wonder that the power which they once possessed has been taken from them; but they had lost it by their own fault. Christ therefore attributes this want of ability to their unbelief, and repeats and illustrates more largely the statement which he had previously made, that nothing is impossible to faith It is a hyperbolical mode of expression, no doubt, when he declares that faith removes trees and mountains; but the meaning amounts to this, that God will never forsake us, if we keep the door open for receiving his grace. He does not mean that God will give us every thing that we may mention, or that may strike our minds at random. On the contrary, as nothing is more at variance with faith than the foolish and irregular desires of our flesh, it follows that those in whom faith reigns do not desire every thing without discrimination, but only that which the Lord promises to give. Let us therefore maintain such moderation as to desire nothing beyond what he has promised to us, and to confine our prayers within that rule which he has laid down.
But it may be objected, that the disciples did not know whether or not the Lord was pleased to cure the lunatic It is easy to reply, that it was their own fault if they did not know; for Christ is now speaking expressly about special faith, which had its secret instincts, as the circumstances of the case required. And this is the faith of which Paul speaks, (1Co 12:9.) How then came it that the apostles were deprived of the power of the Spirit, which they had formerly exercised in working miracles, but because they had quenched it by their indolence? But what Christ said about special faith, in reference to this particular event, may be extended to the common faith of the whole Church.

21.This kind goeth not out, 492 By this expression Christ reproved the negligence of certain persons, in order to inform them that it was not an ordinary faith which was required; for otherwise they might have replied that they were not altogether destitute of faith The meaning therefore is, that it is not every kind of faith that will suffice, when we have to enter into a serious conflict with Satan, but that vigorous efforts are indispensably necessary. For the weakness of faith he prescribes prayer as a remedy, to which he adds fasting by way of an auxiliary. “You are effeminate exorcist,” said he, “and seem as if you were engaged in a mock-battle got up for amusement; 493 but you have to deal with a powerful adversary, who will not yield till the battle has been fought out. Your faith must therefore be excited by prayer, and as you are slow and languid in prayer, you must resort to fasting as an assistance.” 494 Hence it is very evident how absurdly the Papists represent fasting to be the specific method of driving away devils, since our Lord refers to it for no other reason than to stimulate the earnestness of prayer. When he says that this kind of devils cannot be cast out in any other way than by prayer and fasting, he means that, when Satan has taken deep root in any one, and has been confirmed by long possession, or when he rages with unbridled fury, the victory is difficult and painful, and therefore the contest must be maintained with all our might.

Mat 17:22.And while they remained in Galilee The nearer that the time of his death approached, the more frequently did Christ warn his disciples, lest that melancholy spectacle might give a violent shock to their faith. It was shortly after the miracle had been performed that this discourse was delivered; for Mark says that he went from that place to Galilee, in order to spend there the intervening time in privacy; for he had resolved to come to Jerusalem on the day of the annual sacrifice, because he was to be sacrificed at the approaching Passover.
The disciples had previously received several intimations on this subject, and yet they are as much alarmed as if nothing relating to it had ever reached their ears. So great is the influence of preconceived opinion, that it brings darkness over the mind in the midst of the clearest light. The apostles had imagined that the state of Christ’s kingdom would be prosperous and delightful, and that, as soon as he made himself known, he would be universally received with the highest approbation. They never thought it possible that the priests, and scribes, and other rulers of the Church, would oppose him. Under the influence of this prejudice, they admit nothing that is said on the other side; for Mark says that they understood not what our Lord meant. Whence came it that a discourse so clear and distinct was not understood, but because their minds were covered by the thick veil of a foolish imagination?
They did not venture to make any farther inquiry. This must have been owing, in part, to their reverence for their Master; but I have no doubt that their grief and astonishment at what they had heard kept them silent. Such bashfulness was not altogether commendable; for it kept them in doubt, and hesitation, and sinful grief. In the meantime, a confused principle of piety, rather than a clear knowledge of the truth, kept them attached to Christ, and prevented them from leaving his school. A certain commencement of faith and right understanding had been implanted in their hearts, which made their zeal in following Christ not very different from the implicit faith of the Papists; but as they had not yet made such progress as to become acquainted with the nature of the kingdom of God and of the renewal which had been promised in Christ, I say that they were guided by zeal for piety rather than by distinct knowledge.
In this way we come to see what there was in them that deserved praise or blame. But though their stupidity could not entirely be excused, we have no reason to wonder that a plain and distinct announcement of the cross of their Master, and of the ignominy to which he would be subjected, appeared to them a riddle; not only because they reckoned it to be inconsistent with the glory of the Son of God that he should be rejected and condemned, but because it appeared to them to be highly improbable that the grace which was promised in a peculiar manner to the Jews should be set at naught by the rulers of the nation. But as the immoderate dread of the cross, which had suddenly seized upon them, shut the door against the consolation which was immediately added, arising out of the hope of the resurrection, let us learn that, when the death of Christ is mentioned, we ought always to take into view at once the whole of the three days, that his death and burial may lead us to a blessed triumph and to a new life.

And when they were come to the multitude - This took place on the day following the transfiguration, Luk 9:37. This multitude was probably composed of persons who had attended on his ministry, many of whom were his real disciples. With them, as Mark Mar 9:15 informs us, were "scribes questioning with them."That is, they were probably professedly making inquiries about the Saviour, but really attempting to introduce their own sentiments, and to draw them off from him. They probably artfully asked them many questions about his birth, his family, his appearance, his manner of life, and his instructions, all which were contrary to the general expectation respecting the Messiah, and they intended, therefore, to insinuate that such a person could not be the Christ. The people were persuaded that he was the Messiah. and it would not have done to have attacked their opinions openly, but they attempted to gain the same point by sly insinuations. Error is always subtle, and often puts on the appearance of calm and honest inquiry. Well had he compared them to leavens, Mat 16:11-12. The multitude, seeing Jesus coming down, left the scribes, and ran to meet him (Mark). They were amazed, probably because they had not expected to see him there. In their joy at meeting him in this unexpected manner, they "saluted"him (Mark); that is, probably they prostrated themselves before him after the manner of salutation in Eastern countries. See the notes at Luk 10:4. Jesus, seeing the scribes and their artful design, reproved them by asking them why they questioned thus with his disciples, Mar 9:16. Conscious of their guilt and their base purpose, they returned no answer.
A certain man kneeling down to him - That is, saluting him, or showing high regard for him. See the notes at Luk 10:4. It did not imply religious homage, but merely high respect and earnest entreaty.

Lord, have mercy - The word "Lord"here means "Sir,"a title of civility, not implying divinity.
My son - This was an only son (Luke). He was possessed with a devil. This calamity was attended with the following symptoms: he was lunatic (see the notes at Mat 4:24); he was sore vexed; that is, he suffered greatly, or was greatly afflicted; he fell often suddenly, in the manner of persons having epileptic fits; he was dumb - that is, he was mute except when the seizure was coming upon him, for Luke says that when the spirit took him he cried suddenly out; he foamed and gnashed with his teeth, and wasted away, or became poor and emaciated. Luke Luk 9:39 adds of the evil spirit, "it teareth him that he foameth again, and, bruising him, hardly departeth from him;"that is, scarcely departed from him, or he had only short intervals of reason, for so the passage in Luke, "bruising him, hardly departeth from him,"should be translated.

Barnes: Mat 17:16 - -- And I brought him to thy disciples ... - That is, not to the apostles, for they had power over unclean spirits Mat 10:8, but to others of his f...
And I brought him to thy disciples ... - That is, not to the apostles, for they had power over unclean spirits Mat 10:8, but to others of his followers who attempted to work miracles. It is probable that many of his disciples attempted this who were not personal attendants on his ministry, Mar 9:38.

Barnes: Mat 17:17 - -- Then Jesus answered and said, O faithless and perverse generation! - Perverse means that which is twisted or turned from the proper direction; ...
Then Jesus answered and said, O faithless and perverse generation! - Perverse means that which is twisted or turned from the proper direction; and is often used of the eyes, when one or both are turned from their natural position. Applied to a generation or race of people, it means that they hold opinions turned or perverted from the truth, and that they were wicked in their conduct. Jesus applied this, probably, to the Jews, and not to his real disciples.
How long shall I suffer you? - That is, how long shall I bear with you? How long is it necessary to show such patience and forbearance with your unbelief and perversity? This was not so much an expression of impatience or complaint as a reproof for their being so slow to believe that he was the Messiah, notwithstanding his miracles.
Mark adds Mar 9:20-22 that when he that was possessed was brought, the spirit, by a last desperate struggle, threw him down and tore him, and left him apparently dead. He adds further, that the case had existed during the whole life of his son, from a child. This was a case of uncommon obstinacy. The affliction was fixed and lasting. The disciples, seeing the obstinacy of the case - seeing that he was a deaf-mute, wasted away, torn, and foaming - despaired of being able to cure him. They lacked the faith which was necessary; doubted whether they could cure him, and therefore could not.
The father of the child said Mar 9:22, "If thou canst do anything, have compassion on us and help us;"an expression implying a weak faith, a lingering doubt whether he could restore him. Jesus replied to this, "If thou canst believe, all things are possible to him that believeth"Mar 9:23; implying that the difficulty in the case was not that he could not heal him, but that he had not the proper kind and degree of faith with which to come to him. That is, this cure shall be effected if you have faith. Not that his faith would give Jesus the power to heal him, but it would render it proper that he should exert that power in his favor. In this way, and in this only, are all things possible to believers.
The man had faith, Mar 9:24. The father came, as a father should do, weeping, and praying that his faith might be increased, so as to make it proper that Jesus should interpose in his behalf, and save his child.
Help my unbelief, Mar 9:24. This was an expression of humility. If my faith is defective, supply what is lacking. Help me to overcome my unbelief. Let not the defect of my faith be in the way of this blessing.

And Jesus rebuked the devil - The word "rebuke"has the combined force of reproving and commanding. He reproved him for having afflicted the child, and he commanded him to come out of him. Mark Mar 9:25 has recorded the words which he used words implying reproof and command: "Thou dumb and deaf spirit, I charge thee come out of him, and enter no more into him."And the spirit cried, and with a mighty convulsion came out, leaving the child apparently dead. Jesus lifted him up by the hand (Mark), and gave him to his father (Luke).

Jesus told them, in reply, that it was because of their unbelief that they had not been able to cast him out. They were appalled by the difficulty of the case and the obstinacy of the disease. Their faith would not have made it more easy for God to work this miracle, but such was his will - such the way in which he worked miracles, that he required faith in those who were the instruments.

As a grain of mustard-seed - See the notes at Mat 13:31-32. The mustard-seed was the smallest of all seeds. It has been supposed by some, therefore, that he meant to say, If you have the smallest or feeblest faith that is genuine, you can do all things. The mustard-seed produced the largest of all herbs. It has been supposed by others, therefore, to mean, If you have increasing, expanding, enlarged faith, growing and strengthening from small beginnings, you can perform the most difficult undertaking. There is a principle of vitality in the grain of seed stretching forward to great results, which illustrates the nature of faith. Your faith should be like that. This is probably the true meaning.
Ye shall say unto this mountain ... - Probably he pointed to a mountain near, to assure them that if they had such faith they might accomplish the most difficult undertakings - things that at first would appear impossible.

Barnes: Mat 17:21 - -- Howbeit, this kind ... - This kind means this kind of devils - this species of possession. Where they have had long possession where they produ...
Howbeit, this kind ... - This kind means this kind of devils - this species of possession. Where they have had long possession where they produce such painful, fixed, and alarming effects, they can be expelled only in connection with prayer and fasting.
Goeth not out but by prayer and fasting - That is, in order to work miracles of this kind to cast out devils in cases so obstinate and dreadful as this, faith of the highest kind is necessary. That faith is produced and kept vigorous only by much prayer, and by such abstinence from food as fits the mind for the highest exercises of religion, and leaves it free to hold communion with God.

See also Mar 9:30-33; Luk 9:43-45.
And while they abode in Galilee - Galilee, the northern part of Palestine. See the notes at Mat 2:22.
The Son of man shall be betrayed ... - To betray means to deliver up in a treacherous manner. This was done by Judas Iscariot, called for that act the traitor, Mat 26:14-16, Mat 26:47-50. A traitor, or betrayer, is one who makes use of confidence reposed in him for the purpose of delivering him up who puts that confidence in him to the hands of enemies.
And they shall kill him, and the third day he shall be raised again - See Mat 12:40. Mark and Luke add that they understood not that saying, and it was hid from them, and they were afraid to ask him. The reasons of this may have been,
1. They were strongly attached to him, and were exceedingly sorry (Matthew) at any intimation that he was soon to leave them. They learned with great slowness and reluctance, therefore, that he was to be treated in this manner.
2. They were not willing to believe it. They knew that he was the Messiah, but they supposed that he was to be a distinguished prince, and was to restore the kingdom to Israel, Act 1:6. But to be betrayed into the hands of his enemies, and be put to death, appeared to them to be frustrating all these expectations.
3. Though what he said was plain enough, yet they did not understand it; they could not see how he could be the Messiah, and yet be put to death in this manner; nor did they understand it fully until after the resurrection.

Ver. 14-16. The same history is told us both by Mark and Luke, but with considerable difference; we have it, Mar 9:17,18 , thus, And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit; and wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out, and they could not. As an introduction to this, Mark saith, Mar 9:14-16 , that when our Saviour came to his disciples, he saw a great multitude about them, and the scribes questioning with them. And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him. And he asked the scribes, What question ye with them? Luke gives us this account, Luk 9:37-40 , And it came to pass, that on the next day, when they were come down from the hill, much people met him. And, behold, a man of the company cried out, saying, Master, I beseech thee, look upon my son: for he is mine only child. And, lo, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth again, and bruising him hardly departeth from him. And I besought thy disciples to cast him out; and they could not. When our Lord went up to the mountain where he was transfigured, he left at the foot of it the multitudes, and nine of his apostles, he took only three with him. How long he stayed there no evangelist tells us. The multitude and his disciples stayed waiting for his coming, probably not far of; some of the scribes were got to them, and they were arguing together. The day after our Lord, and Peter, James, and John, were come down from the mount, they go to the multitude, who received him with great passion, and saluted him. He begins to inquire what they were discoursing about; but was by and by interrupted with a certain man, who comes and falls down upon his knees before him, begging mercy for his son, who (as Matthew reports his condition) was lunatic and sore vexed, often falling into the fire, and often into the water. Mark saith, he had a dumb spirit, that it tore him, he often foamed and gnashed with his teeth. Luke saith, that it was the man’ s only child, that he had a spirit, that he cried out, it tare him, he foamed, and was bruised by it, &c. By the description of this young man’ s disease, it appeareth to have been what we call the falling sickness, wherein men fall down, foam, and beat themselves. With this disease the devil joined, so as at certain times of the moon this disease took him, and the devil acting with it, he was dumb, at least for the time, and fell sometimes into the fire, sometimes into the water, foamed, gnashed with his teeth, tore himself: this seems to have been his condition. The father (during Christ’ s absence) had attempted a cure by his disciples, but the text saith they could not (the reason we shall hear afterward); upon this he crieth unto Christ for his help.

Ver. 17,18. Mark relates this part of the history much more largely, Mar 9:19-27 , he answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? Bring him unto me. And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming. And he asked his father, How long is it ago since this came unto him? And he said, Of a child. And oft times it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us. Jesus said unto him, if thou canst believe, all things are possible to him that believeth. And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief. When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him. And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead. But Jesus took him by the hand, and lifted him up; and he arose. Luke relates this shorter, but addeth nothing to what is in the other evangelists, Luk 9:41,42 . Then Jesus answered and said, O faithless and perverse generation. Christ here calls them so not with respect to justifying faith, but that faith which respected the Divine power as to working miracles. Every revelation of the Divine will is the object of faith; Christ had revealed to the Jews that he was sent of God, and furnished with such a power; this the Jews, and particularly the scribes, did not believe. The faith of the father of this child was but very weak in the case; no more, as we shall see afterwards, was the faith of the disciples; so as he may be understood to respect them all, though in different degrees. He calls them perverse, because they had so often seen and experienced his power of this nature, yet their faith was not clear and strong. He biddeth that the young man should be brought to him, and it was done. And when he saw him, ( saith Mark), straightway the spirit tare him, & c. Our Saviour could easily have prevented this, but probably he suffered it that the miracle might be more evident. However, it letteth us see how hardly the devil parteth with his possession in us in any degree, and how ready he is to run to the length of his line in doing us mischief. Christ asked his father how long he had been so vexed; his father tells him, from a child. By this also the miracle was more illustrious, which probably was the reason why Christ propounded the question. No evils are too inveterate for Christ to remove. The father renewth his request, and in it showeth the weakness of his faith: If (saith he) thou canst do any thing. His coming to Christ, and crying to him, argued that he believed he could do something; his saying if thou canst do any thing speaks the weakness of his faith. Christ tells him, if he could believe, all things are possible. Nothing ties God’ s hands but his creatures’ unbelief. It is said, that Christ could not in Capernaum do many mighty works because of their unbelief. Upon this the father cries out,
Lord, I believe; help thou mine unbelief Men may truly believe, and yet have a mixture of unbelief. God rewards a weak faith, to souls labouring under the sense of their weakness, and desiring an increase of strength. Christ rebukes the spirit (called a dumb and deaf spirit, because it made the person such that was thus affected with it). Christ commands the spirit out, and so to come out as never more to enter into him. The evil spirit roars, rends him, comes out, and leaveth him as one dead: which still confirmeth us in his malice to mankind; he will do what harm he can when he cannot do us the harm he would.

Ver. 19-21. Mark repeats only what we have here Mat 17:19,21 . The reason assigned here by our Saviour why his disciples could not cast out this devil, was their unbelief; not their total want, but the weakness of their faith. Christ here again lets us see the power of faith, and the mischief of unbelief. I take the plain sense of the text to be this, That there is nothing which may tend to the glory of God, or to our good, but may be obtained of God by a firm exercise of faith in him. Whether our Saviour here speaketh of a faith of miracles, or no, I will not determine; I rather think that he speaketh here of any true faith: we must have the power and promise of God for its object. The promise of working miracles by a Divine power committed to them, was a particular promise made to the disciples, Mat 10:1-42 , and so was only the object of their faith. But I take our Saviour’ s words to extend to a further latitude, though, as to miraculous operations, it was only applicable to them. There is nothing which God hath promised to give or bestow on any but faith will obtain from him, if attended by a fervent prayer, to which fasting is subservient, as preparing us to it. There are some things which are obtained by a stronger faith, and by more fervent and importunate prayers, than others are. A mercy sometimes seem to us to come out of the hand of God with more difficulty, and wrestling for it; but there is nothing within the latitude of a promise, but is to be done and obtained by the vigorous exercise of faith, and by fervent and importunate prayer. The apostles had yet but a weak and imperfect faith, and they had not used such fervent and importunate prayer in this case as they ought to have done; thence did this work appear so difficult unto them.

Ver. 22,23. Mark saith, Mar 9:30-32 . And they departed thence, and passed through Galilee; and he would not that any man should know it. For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day. But they understood not that saying, and were afraid to ask him. Luke saith, Luk 9:44,45 , he said unto them, Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men. But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying. It is said that Christ taught his disciples as they were able to hear, Mar 4:33 . He tells them, Joh 16:12 , he had many things to say unto them, but they could not bear them at that time. Christ a long time concealed the doctrine of his passion, and resurrection from the dead, from them, until he had confirmed them in the great point of his Divine power, and his being the true Messiah; now he begins to deliver this doctrine unto them, that what they should now soon see might not weaken their faith in him as the Messiah and the Son of God; partly in regard of that inveterate opinion which had possessed the generality of the Jews, that the Messiah should be a temporal prince, and should deliver the Jews from that servitude under which they were, and had for a long time been; partly in regard of the difficulty to conceive how he who was the Son of God could die. Once or twice before therefore he had begun to speak to them about his passion, Mat 16:21 . Moses and Elias had some discourse with him about it, Luk 9:31 . The text saith, they understood it not; it was hid from them; they perceived it not; they were afraid to ask him.
They were exceeding sorry: possibly they were sorry that they could not understand it, and reconcile it to the notion of the Messias they had drank in; for it seems hard to assert they were sorry for what Christ said about his suffering, because the Scripture saith, they understood it not, thinking our Saviour had not spoken plainly of a matter of fact which should be, but that he intended something else besides what his words seemed plainly to import.
Lightfoot: Mat 17:15 - -- Lord, have mercy on my son: for he is a lunatic, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.  [He i...
Lord, have mercy on my son: for he is a lunatic, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.  
[He is lunatic.] Luk 9:39; a spirit taketh him; Mar 9:17; hath a dumb spirit.  
I. He that is skilled in the Talmudic writings will here remember what things are said concerning a deaf and mad man; concerning whom there is so much mention in their writings.  
"There are five who do not pay the Trumah; but if they do, their Trumah is no Trumah: the deaf and dumb, the lunatic;" etc. "Any one is fit to sacrifice a beast, except a dumb and deaf, a lunatic, and a child ": and very many passages of this nature, etc. I have rendered deaf and dumb; according to the sense of the masters, who, in the first place cited, do thus interpret the word; "concerning which the wise men speak, is he who neither heareth nor speaketh." See there the Jerusalem Gemara, where, among other things, this occurs not unworthy our noting; "That all the sons of R. Jochanan Ben Gudgoda were deaf and dumb."  
II. It was very usual to the Jews to attribute some of the more grievous diseases to evil spirits, specially those wherein either the body was distorted, or the mind disturbed and tossed with a phrensy.  
" If any one, vexed with an evil spirit, shall say, when the disease did first invade him; Write a bill of divorce for my wife," etc.  
" If any, whom Kordicus vexeth; say, Write a bill of divorce for my wife," etc. " Kordicus; say the Glossers, is a demon, which rules over those that drink too much new wine. What is 'Kordicus?' Samuel saith, When new wine out of the press hath caught any one." Rambam, upon the place, hath these words; " Kordicus is a disease, generated from the repletion of the vessels of the brain, whereby the understanding is confounded; and it is a kind of falling-sickness." Behold the same a demon and a disease! to which the Gemarists applied exorcisms and a diet.  
"Shibta is an evil spirit, who, taking hold on the necks of infants, dries up and contracts their nerves."  
"He that drinks up double cups, is punished by the devils."  
From this vulgar opinion of the nation, namely, that devils are the authors of such kind of diseases, one evangelist brings in the father of this child, saying of him he is lunatic; another, he hath a spirit. He had been dumb and deaf from his birth; to that misery was added a phrensy, or a lycanthropy, which kind of disease it was not unusual with the nation to attribute to the devil; and here, in truth, a devil was present.

Lightfoot: Mat 17:17 - -- Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? How long shall I suffer you? Bring him hither to...
Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? How long shall I suffer you? Bring him hither to me.  
[O faithless and perverse generation, etc.] the edge of these words is levelled especially against the scribes (see Mar 9:14); and yet the disciples escaped not altogether untouched.  
Christ and his three prime disciples being absent, this child is brought to the rest to be healed: they cannot heal him, partly, because the devil was really in him; partly, because this evil had adhered to him from his very birth. Upon this the scribes insult and scoff at them and their master. A faithless and perverse generation; which is neither overcome by miracles, when they are done, and vilify, when they are not done! The faith of the disciples (Mat 17:20) wavered by the plain difficulty of the thing, which seemed impossible to be overcome, when so many evils were digested into one, deafness, dumbness, phrensy, and possession of the devil: and all these from the cradle.

Lightfoot: Mat 17:20 - -- And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto thi...
And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.  
[Faith as a grain of mustard seed, etc.] As a seed of mustard; or as a drop of mustard; in Talmudic language. See Mat 13:23.  
[Ye shall say to this mountain, etc.] see what we note at Mat 21:21.

Lightfoot: Mat 17:21 - -- Howbeit this kind goeth not out but by prayer and fasting.  [This kind goeth not out but by prayer and fasting.] It is not much unlike thi...
Howbeit this kind goeth not out but by prayer and fasting.  
[This kind goeth not out but by prayer and fasting.] It is not much unlike this, which is said, By reason of an evil spirit a singular or religious man may afflict himself with fastings.

And when he was come. Peter, by wishing to remain on the holy mount, preferred his own gratification to the good of many. But true charity seeketh not its own advantage only; what therefore appeared good to Peter, did not appear so to Christ, who descends from the mountain, as from his high throne in heaven, to visit man. (Origen)

I brought him to thy disciples. By these words the man here mentioned privately accuses the apostles, though the impossibility of the cure is not always to be attributed to the weakness of God's servants, but sometimes to the want of faith in the afflicted. (St. Jerome) ---
Stand astonished at the folly of this man! how he accuses the apostles before Jesus! But Christ frees them from this inculpation, imputing the fault entirely to the man himself. For it is evident, from many circumstances, that he was weak in faith. Our Saviour does not inveigh against this man alone, not to wound his feelings too sensibly, but against the whole people of the Jews. We may infer, that many of the bystanders entertained false notions of his disciples, from these words of deserved reproach: O! unbelieving and incredulous generation, how long shall I be with you? In which words, he shews us how much he wished for his passion, and his departure hence. (St. John Chrysostom) ---
We must not imagine that our Saviour, who was meekness and mildness itself, uttered on this occasion words of anger and intemperance. Not unlike a feeling and tender physician, observing his patient totally disregarding his prescriptions, he says, How long shall I visit you; how long shall I order one thing, and you do the contrary? Thus Jesus is not angry with the man, but with the vices of the man; and in him he upbraids the Jews, in general, for their incredulity and perversity. (St. Jerome) ---
The general sentiment is, that these reproaches are limited to the people; some extend them to the apostles. See below, ver. 19. (Bible de Vence)

Haydock: Mat 17:18 - -- Why could not we? The disciples began to apprehend that they had incurred their Master's displeasure, and had thereby lost their power of working mi...
Why could not we? The disciples began to apprehend that they had incurred their Master's displeasure, and had thereby lost their power of working miracles. They come therefore secretly to Jesus Christ, to learn why they could not cast out devils. He answered them, that it was their want of faith, which probably failed them on this occasion, on account of the difficulty of the cure, little reflecting that the virtue of the Lord, which worked in them, was superior to every possible evil of both mind and body. ---
St. Hilary is of opinion, that during the absence of Christ on the mountain, the fervour of the apostles had begun to abate. (Jansenius)

Haydock: Mat 17:19 - -- If you have faith as a grain of mustard-seed. Christ insinuates to his apostles, as if they had not yet faith enough to work great miracles, which r...
If you have faith as a grain of mustard-seed. Christ insinuates to his apostles, as if they had not yet faith enough to work great miracles, which require a firm faith joined with a lively confidence in God. The mustard-seed is brought in with an allusion to its hot and active qualities. (Witham) ---
That is, a perfect faith; which, in its properties and its fruits, resembles the grain of mustard-seed in the parable. (Chap. xii. 31.) (Challoner) ---
By faith is here understood, not that virtue by which we assent to all things that are to be believed of Christ, the first, of the theological virtues, in which the apostles were not deficient, but that confidence in the power and goodness of God, that he will on such an occasion exert these, his attributes, in favour of the supplicant. To have a true faith of this kind, and free from all presumption, is a great and high privilege, which the Holy Ghost breathes into such only as he pleases. (Jansenius) ---
Examples of this efficacious faith are given by St. Paul. (Hebrews chap. ii.) St. Gregory of Neo-Cæsarea is also related, by Eusebius and Ven. Bede, to have removed by the efficacy of his faith a rock, which obstructed the building of a church; thus literally fulfilling the promise of Jesus Christ. (Tirinus) ---
The faith of the apostles, especially of those that had not been present at the transfiguration, was not perfect and complete in all its parts, till after the resurrection and ascension of Jesus Christ, and the descent of the Holy Ghost. (Haydock) ---
St. Jerome understands by mountains, things the most difficult to be effected.

Haydock: Mat 17:20 - -- See here the efficacy of prayer and fasting! What the apostles could not do, prayer accompanied with fasting can effect. How then can that be genuin...
See here the efficacy of prayer and fasting! What the apostles could not do, prayer accompanied with fasting can effect. How then can that be genuine religion, which makes fasting an object of ridicule? We see also here that the true Church in her exorcisms follows Scripture, when she uses besides the name of Jesus, many prayers and much fasting to drive out the devils, because these, as well as faith, are here required. (Bristow)

Jesus then taking the road to Jerusalem with his disciples, and whilst they were in Galilee, which they had to pass through, he spake to them of his suffering, death, and resurrection. (Bible de Vence)

They were troubled exceedingly, not being able to comprehend the mystery of Christ's sufferings and death, which were so opposite to the nations they had of the glorious kingdom of the Messias. (Witham) ---
This grief was the consequence of their attachment to their divine Master. They were ignorant, as St. Mark and St. Luke notice, of the word that was spoken. They full well understood that he would be put to death, but did not sufficiently comprehend the shortness of his rest in the grave, the nature of his triumphant resurrection, nor the inestimable benefits which his death would bring on the world. (St. John Chrysostom, hom. lix.)

They that received the didrachmas, ( Greek: ta didrachma ) in value about fifteen-pence of our money. (Witham) ---
A tax, according to some, laid on every person who was twenty years of age, for the service of the temple. See Exodus xxx. St. John Chrysostom thinks it was paid for the first-born only, whom the Lord would have redeemed for the first-born of the Egyptians, whom he slew. Others think it was a tribute paid to the Romans, as Christ, in ver. 24, seems to insinuate, by mentioning the kings of the earth; and the Jews were tributary to them at this time. In ver. 24, the evangelist uses the word Greek: Kensos, taken from the Latin census, or tax.

And when they were come to the multitude,.... Which was on the next day, as in Luk 9:37 when Christ and his three disciples, Peter, James, and John, came down from the mount to the other nine, with whom the multitude of the people were; during their stay on the mountain,
there came to him a certain man; who was, as Mark says, "one of the multitude"; and as Luke, "a man of the company": who had applied to the nine disciples on the behalf of his son, but without success, and was waiting till Christ came from the mount; who when he saw him, made up to him, and
kneeling down to him in the manner of a supplicant, doing him homage and worship; hereby showing his great esteem of him, and veneration for him,
and saying the following words:

Gill: Mat 17:15 - -- Lord, have mercy on my son,.... He addressed him with great marks of honour and respect, not only by gesture, but by words; he craves mercy, pity, and...
Lord, have mercy on my son,.... He addressed him with great marks of honour and respect, not only by gesture, but by words; he craves mercy, pity, and compassion; for the case he had to present, was a miserable one; and his earnestness and importunity he hoped might be excused, since it was for a child of his own. Luke adds "for he is mine only child"; and therefore his affection for him must be thought to be very strong, and he greatly concerned for its grievous affliction, and earnestly desirous of its health and life.
For he is lunatic: not a mad man, but troubled with the epileptic disease; upon which, as on madness or lunacy, the changes and full of the moon have an influence: hence the next clause,
and sore vexed, is rendered in the Arabic version, "and sore vexed at the beginning of full moons"; at which times, he had very grievous and frequent fits of his disorder:
for ofttimes he falleth into the fire, and oft into the water: which shows it to be the "epilepsy", or "falling sickness", he was afflicted with; which, whenever it seized him, whether by the fireside, or by the side of a river or brook, or any place of water, or in any other dangerous situation, he fell into it, not being able to help himself, or avoid any danger to which he was exposed. A larger account of this child's disorder, and of the circumstances of his cure, are related by Mar 9:17 where this case will be more fully considered. See Gill on Mar 9:17. See Gill on Mar 9:18.

Gill: Mat 17:16 - -- And I brought him to thy disciples,.... To the nine, whilst Christ was with the other three upon the mountain: no doubt but his design was to bring hi...
And I brought him to thy disciples,.... To the nine, whilst Christ was with the other three upon the mountain: no doubt but his design was to bring him to Christ first; but he being absent, he applied to his disciples, and, desired them to make use of their power to heal him; and which they attempted, but without success:
and they could not cure him. This he said, partly to show the malignity and stubbornness of the disease, and partly to accuse the disciples of weakness; when he himself was as much in fault as they, as the following words show. Here the Jew w insults, and charges with contradiction, that in one place it should be said, that Jesus gave his disciples power to cast out unclean spirits, and here all the disciples could not cast a spirit out of one little child: but without any reason; let it be observed, that "all" the disciples were not present, the three principal ones were with Christ; besides, this was not owing to want of power in them, which Christ had conferred on them, and which they often made use of with success: but partly to their own unbelief, and partly to the unbelief of the father of this child, and others with him, as appears from what follows: and it is clear from Mark, that when he came to Christ, he had but little faith; he says to him, "if thou canst do anything, help us"; and after Christ had talked with him about his faith, he could only say, "Lord, I believe, help mine unbelief".

Not to the disciples, but to the father of the child; see Mar 9:19 and those that were with him, and the Scribes that were present, disputing with the disciples, upbraiding them with their weakness, and triumphing over them: "O faithless and perverse generation"; a way of speaking, which is never used of the disciples, and indeed could not be properly said of them; for though they often appeared to be men of little faith, yet not faithless; nor were they so rebellious, stubborn, and perverse, as here represented, though there was a great deal of perverseness in them: but the characters better suit the body of the Jewish nation, who, on account of the incredulity of this man, and those that were present, being of the same temper with them, are exclaimed against in words, which were long ago spoken of their ancestors, Deu 32:5 and from whence they seem to be taken.
How long shall I be with you? how long shall I suffer you? Upbraiding them with the length of time he had been with them, in which so many wonderful works had been done among them, and yet they remained unbelieving and incorrigible; and intimating, that his patience and longsuffering would not always continue; and that in a short time, he should be gone from them, and they should no longer enjoy the benefit of his ministry and miracles, but wrath should come upon them to the uttermost: but however, whilst he was with them, notwithstanding all their unbelief and obstinacy, he should go on to do good; and therefore says,
bring him hither to me, meaning the lunatic child. These words also are directed, not unto the disciples, but to the father of the child; for so it is said in Luk 9:41 "bring thy son hither"; and so the Syriac renders it here

And Jesus rebuked the devil,.... The words may indeed be rendered, "and Jesus rebuked him, and the devil departed out of him"; so the Vulgate Latin, and the Oriental versions; but the sense our version gives is certainly right; for it was not the father of the child Christ rebuked for his unbelief; this he had done already; nor the lunatic himself, as some have thought, either for his unbelief, or because he was possessed by the devil, for some sins of his own; which is not likely, since he was so from a child, and perhaps not now in his right mind, and capable of any rebuke: besides, the Evangelists Mark, and Luke expressly say, that he "rebuked the foul", or "unclean spirit": for though it was a natural disease which attended this child, yet he was afflicted with it in a preternatural way, by the means of Satan; who, by divine permission; had a power of inflicting bodily diseases: and that this disease was effected by him, is clear from the manner of curing, by the dispossession of him; for when
he departed out of him; at the command of Christ, whose power he could not withstand, but was obliged, whether he would or not, to obey;
the child was cured from that very hour; directly, immediately, and continued well, and in good health. Hence the word rendered lunatic, in Mat 17:15 is in several Oriental versions, translated in the sense of "demoniac", or one possessed with a devil. The Arabic version renders it, "he is with a demon": the Persic thus, "on whom a demon hath power"; and the Ethiopic after this manner, "an evil demon takes hold on him". And it is usual with the Jews, to ascribe diseases to evil spirits; and perhaps this uncommon dispensation in the times of Christ, may give rise to such a notion; particularly, they ascribe this very same disease of the "epileptic", or "falling sickness", to the same cause, which they call x "Kordicus", or "Cardiacus", the "Cardiac" passion, which one of their commentators y explains thus.
"It is a disease which proceeds from the repletion of the vessels of the brain, whereby the understanding is confounded; wherefore it is one of the sorts
Says another z of them,
"It is
To which others agree, saying a, that one attended with this disorder, is one,
"whose understanding is confounded,
From whence it is clear, that with them, the disease and the demon go by the same name; and that the former is from the latter.

Then came the disciples to Jesus apart,.... Or "secretly", as the Vulgate Latin, and Munster's Hebrew Gospel read; that is, privately, and when alone; and as Mark says, "when he was come into the house"; and was by himself, then came the nine disciples to him, to converse with him about this matter,
and said unto him, why could not we cast him out? That is, the devil, and so cure the lunatic; the Syriac and Persic versions render it, "why could not we heal him?" The lunatic; which only could be done by casting out the demon: they were concerned, fearing they had lost the power which Christ had bestowed on them, and wanted to know what they had done, which had deprived them of it; and what should be the cause of their late unsuccessful attempt, when they had so frequently triumphed over the unclean spirits, that were subject to them. Though they might have learned from the answer Christ gave to the father of the lunatic, and the general character of the Jewish nations in that answer, the true reason of their own inability; but this they took no notice of, imagining it belonged entirely to others, and not to them.

Gill: Mat 17:20 - -- And Jesus said unto them, because of your unbelief,.... The Arabic and Ethiopic versions read, "because of your little faith", or "the smallness of yo...
And Jesus said unto them, because of your unbelief,.... The Arabic and Ethiopic versions read, "because of your little faith", or "the smallness of your faith"; and so does one Greek manuscript; and which is what is doubtless meant by their unbelief; for they were not altogether destitute of faith, but their faith was very low, and their unbelief very great. Christ says, not because of the unbelief of the parent of the child, and those that were with him, though that also was a reason; but because of their unbelief, being willing to convince them of their unbelief, as he had done the father of the child, who had confessed it, and desired it might be removed from him: but lest they should think they had lost their power of doing miracles, Christ adds;
for verily I say unto you, if ye have faith as a grain of mustard seed; which was a very small seed, the least of all seeds, and is used very often proverbially by the Jews, to signify anything of a small quantity or weight b, and is sometimes used of faith, as here; so speaking of the congregation of Edom, meaning the Christians, they c say,
"they have not
And it is used in like sense in other eastern nations; and by Mahomet in his Alcoran d, who says,
"We will appoint just balances in the day of resurrection, neither shall any soul be injured at all, although the merit or guilt of an action be of the weight of "a grain of mustard seed".''
So that it has no reference to the quality of mustard seed, being hot and acrimonious; which has led some interpreters wrong, to compare faith unto it, for its liveliness and fervency: when our Lord only means, that if his apostles had ever so small a degree of faith in exercise, which might be compared for its smallness to this least of seeds, such an effect as he after mentions would follow; and which therefore is to be understood, not of an historical faith, by which men assent to all that is in the Bible as true; nor of a special, spiritual faith, by which souls believe in Christ, as their Saviour and Redeemer; for of neither of these can the following things in common be said; but of a faith of miracles, peculiar to certain persons in those early times, for certain reasons; which such as had but ever so small a degree of, as the apostles here spoken to might say, as Christ observes to them,
ye shall say to this mountain; pointing perhaps to that he was just come down from, which might be in sight of the house where he was,
remove hence to yonder place, and it shall remove: meaning, not that it would be ordinarily or ever done in a literal sense by the apostles, that they should remove mountains; but that they should be able to do things equally difficult, and as seemingly impossible, if they had but faith, when the glory of God, and the good of men, required it. So that it does not follow, because the apostles did not do it in a literal sense, therefore they could not, as the Jew insultingly says e; since it was meant that they should, and besides, have done, things equally as great as this, and which is the sense of the words. So the apostle expresses the faith of miracles, by "removing mountains", 1Co 13:2 i.e. by doing things which are difficult, seem impossible to be done: wherefore Christ adds,
and nothing shall be impossible to you; you shall not only be able to perform such a wonderful action as this, were it necessary, but any, and everything else, that will make for the glory of God, the enlargement of my kingdom and interest, the confirmation of truth, and the good of mankind.

Howbeit, this kind goeth not out,.... The Vulgate Latin renders it, "is not cast out"; and so do the Arabic version, and Munster's Hebrew Gospel; and which confirm the more commonly received sense of these words, that they are to be understood of that kind of devils, one of which was cast out of the lunatic, and was of the worst sort, of a fierce and obstinate kind; and having had long possession, was not easily ejected: and that there is a difference in devils, some are worse and more wicked than others, is clear from Mat 12:45 and not of that kind of miracles, or kind of faith to the working of such miracles. Moreover, the above versions, as they fitly express the word
but by fasting and prayer: that is, in the exercise of a miraculous faith, expressed in solemn prayer to God, joined with fasting. It seems that Christ not only suggests, that faith was greatly wanting in his disciples; for which reason they could not cast out the devil, and heal the lunatic; but they had been wanting in prayer to God, to assist them in the exercise of their miraculous gifts; and that whilst Christ, and the other three disciples were on the mount, they had been feasting and indulging themselves with the people, and so were in a very undue disposition of mind, for such extraordinary service, for which our Lord tacitly rebukes them. This agrees with the notions of the Jews, who think that, by fasting, a divine soul f

And while they abode in Galilee,.... Munster's Hebrew Gospel reads it
Jesus said unto them, the son of man shall be betrayed into the hands of men: some copies read, "sinful men"; and so the angels report the words, in Luk 24:7 by whom may be meant the Gentiles, who, by the Jews, were reckoned very wicked men, and called sinners of the Gentiles. Now Christ intimates, that the son of man, meaning himself, should be betrayed by the Jews, into the hands of the Gentiles; than which, with the Jews, nothing was reckoned a fouler action, or a viler crime; their canons run thus h:
"It is forbidden to betray an Israelite into the hands of the Gentiles, whether in his body or in his substance; and though he may be a wicked man, and a ringleader in sin, and though he may have oppressed and afflicted him; and everyone that betrays an Israelite into the hands of the Gentiles, whether in his body, or in his substance, has no part in the world to come.''
They forgot this rule, when they delivered Christ to Pontius Pilate. They go on to observe, that
"it is lawful to kill a betrayer in any place, even at this time, in which they do not judge capital crimes; and it is lawful to kill him before he betrays; but when he says, lo! I am about to betray such an one in his body, or in his substance, though his substance is small, he exposes himself to death; and they admonish him and say to him, do not betray: if he is obstinate, and says I will betray him, it is commanded to kill him; and he that is first to kill him, is a worthy man,''

Gill: Mat 17:23 - -- And they shall kill him,.... Put him to death, with the death of the cross; for the angels in rehearsing these words, affirm, that Christ told his dis...
And they shall kill him,.... Put him to death, with the death of the cross; for the angels in rehearsing these words, affirm, that Christ told his disciples at this time, and in this place, whilst they were in Galilee, that he should be crucified, Luk 24:7.
And the third day he shall be raised again: this he said for their comfort; and it is observable, that when Christ speaks of his rising again, he makes mention of the exact time, the third day, on which he should rise, according to the types and prophecies of the Old Testament:
and they were exceeding sorry: that he should be betrayed into the hands of the Gentiles, fearing that another nation would come, and take away, and possess the worldly kingdom and grandeur they were dreaming of; and that he should die at all; and much more that he should die such a cruel and ignominious death, as that of the cross. They seem to have overlooked, and to have taken no notice of his rising again from the dead; which might have administered comfort to them, and have relieved them under their melancholy apprehensions of things; but this they understood not, nor indeed truly any part of what he had said; so Mark and Luke intimate: but then it may be said, how came they to be so very sorrowful, if they did not know what was said? To which may be replied, that this might be the reason of their sorrow, because they did not understand what he said, and they were afraid to ask; they could not tell how to reconcile the betraying of him into the hands of men, and his sufferings and death, with their notions, that the Messiah should abide for ever, and should set up a temporal kingdom, in great splendour and magnificence; and what he meant by rising again from the dead, they could not devise; they could not tell whether all this was to be understood in a literal, or mystical sense.
