The next five sections (vv. 1-4, 5-8, 9-11, 12-13, and 14-18) continue the theme of Judah's guilt from the previous chapter. These pericopes have obvious connections with one another, but they were evidently originally separate prophecies. Verses 1-4 are particularly ironic.
17:1 The indictment against Judah for her deeply ingrained sins was written permanently on the people's hearts (cf. Job 19:24). It stood etched there and, also figuratively, on their most prominent places of worship, the pagan altars throughout the land. Sins engraved on the heart pictures the chief characteristic that marked the inner life of the people, which was indelible sin. When Yahweh had given Israel the covenant at Mount Sinai, He inscribed it on tablets of stone (Exod. 24:12; 31:18). But now what was authoritative for the people was sin that they had inscribed on tablets of flesh.
Rather than blood on the horns of the brazen altar in the temple courtyard testifying to the people's commitment to Him, the Lord saw their sins marking the horns of their pagan altars (cf. 7:21-26; Amos 4:4-5). The brazen altar was a place of sacrifice where their sins could be removed, but the horns of their altars had become places of sacrilege where their sins stood recorded.
". . . the people's heart has guilt not only written all over it but etched into it, engraved . . . beyond erasure."267
In the future God promised to write His law on His people's hearts (31:31-34), but until then their sins were what marked their hearts. Then He would remember their sins no more, but now they remained recorded and unforgiven.
17:2 The people of Judah thought of their idols as frequently and as lovingly as they thought of their children.268They mixed the worship of pagan deities with their worship of Yahweh and even gave those gods credit for what belonged to the Lord. Instead of worshipping on high hills where pagan altars stood, the Judahites were to worship on the holy hill where the temple stood.
17:3 Jerusalem stood like a mountain surrounded by countryside. Normally a city on such a site would be secure from invaders. But Yahweh would turn over His people's wealth and treasures, and their pagan places of worship (really sin), to their enemy (cf. 15:13). The idolaters thought the places where their shrines stood belonged to the gods they worshipped there, but Yahweh really owned them and would turn them over to Judah's invader.
17:4 The Judeans would voluntarily let the inheritance that God had given them, namely, their land, drop into their enemy's hands (cf. 15:14; 2 Kings 25:13-17). They would serve this enemy in a strange land because they had aroused the Lord's anger by their sin.
"The irony is clear: Judah has forsaken or abandoned her covenantal inheritance. Therefore Yahweh will abandon Judah to her enemies, and she will find herself exiled from her inheritance in a land that she had not known."269
Verses 5-8 seem to be proverbs that the writer placed together to make his own point. They contrast the wickedness of trusting man with the blessedness of trusting God.
17:5 Yahweh announced a curse on anyone who trusts in flesh (humanity in its frailty) rather than in Him (cf. 2:18; Isa. 31:3). While this announcement has universal scope, in this context Jeremiah applied it to the covenant people especially. Judah had trusted in people rather than in Yahweh. Turning away from Him (abandoning His covenant) brought His curse.
17:6 The person who would trust in man rather than in God would experience a dry, unproductive, and lonely existence (cf. Ps. 1:4), like the dwarf juniper of the desert. Salty land lacked fertility and life, as is observable to this day around the Dead Sea. Of course, such people may flourish for a season (cf. 12:1-2), but over a lifetime they normally wither.
17:7 The Lord also announced a blessing on anyone who trusts in Him, namely, all who acknowledge Him as their Lord and surrender to Him.
17:8 Such a person would experience a constantly growing and fruitful life. He would enjoy stability, confidence, mental health, freedom from anxiety even in trying times, and a consistently radiant testimony before others (cf. Ps. 1:3). An essential difference between a bush and a tree is its root system. A tree can outlast a drought and continue to bear fruit whereas a bush cannot (cf. Matt. 13:6, 21).
"These verses are a reflection of Jeremiah's own experience. He had known the drought experience when Yahweh seemed to him like a deceitful brook, like waters that failed when sought by a thirsty man (15:18). . . . In 17:5-8 we see a man who has repented from foolish thoughts of despair and consternation before the powerful pressure of public opinion. He had learned to trust Yahweh rather than the opinions of men. The present passage is to be understood as his personal affirmation that he has survived his dry period. Indeed these verses constitute a response to Yahweh's call to repentance in 15:19-21."270
Verses 9-11 also appear to have been well-known proverbs that Jeremiah used for his own purposes. Many scholars classify this passage as one of Jeremiah's "confessions."
"If there is such blessing in trusting God, then why do people so generally depend on their fellow humans? Why is it that the blessed are not more numerous than the cursed? The answer lies in the innate depravity of the human heart (v. 9)."271
17:9 The Old Testament frequently uses "heart"(Heb. leb) to identify the source of a person's thinking and acting. It describes the root of unconscious as well as conscious motivation.
The human heart is deceptive; we may think we know why we do something, but really we may be doing it for another reason. It is naturally sick, really totally depraved, and in need of healing. No one really understands his or her own heart, nor do we understand why our hearts behave as they do.
"Unregenerate human nature is in a desperate condition without divine grace . . ."272
17:10 Even though we cannot understand out hearts, the Lord searches them and knows our inner thoughts and motives.273He gives to each person what he or she really deserves. He judges on the basis of works because what we do reflects what we really value, the condition of our hearts.
17:11 It is possible to earn a fortune unjustly, like a partridge (or grouse, Heb. qore') that incubates the eggs of another bird.274But such a fortune is fleeting (cf. Prov. 23:4-5), and such a person is really a fool. The adopted baby bird will fly away when it eventually learns that it is different from its foster parent. Similarly ill-gotten wealth normally leaves the one who does not earn it, and the person who tries to claim that he did earn it ends up looking like a fool (cf. Luke 12:20-21).
Dwelling on the sinfulness of people and the deceitfulness of the heart needs balancing with even greater attention to the glory of God Himself. Jeremiah changed his perspective and so avoided more discouragement.
17:12 The true place of worship for God's people since Solomon had always been the temple in Jerusalem. The ancients regarded this temple as Yahweh's throne on earth.
17:13 This had been true because Yahweh Himself was the hope of His people (cf. 14:8; 50:7). Consequently all who break covenant and forsake Him, the fountain of living water (2:13), will suffer humiliation and will become the objects of His judgment. The Lord keeps a record of those who turn away from Him (cf. v. 1).
Verses 14-18 are another of Jeremiah's "confessions."The guilt of Judah is prominent in the first part of this chapter, but now the innocence of Jeremiah presents a contrast.
17:14 The prophet prayed to Yahweh, the one he praised, for healing and deliverance. Earlier he had spoken of his pain that refused healing (15:18).
17:15 The Judahites kept asking Jeremiah for evidence that what he was predicting would happen. They implied that because his prophecies had not yet materialized they would not.
17:16 Jeremiah vindicated himself by citing three things. He knew that the Lord understood that he was not eager to escape his calling, he did not enjoy announcing judgment, and his messages had not come from his own mind but from the Lord (cf. 2 Pet. 1:21).
17:17 Since Yahweh was Jeremiah's refuge from criticism and discouragement, the prophet asked Him not to frighten him (by appearing to desert him). Jeremiah was not always so trusting (cf. 20:7-12).
17:18 He prayed for God to humiliate his persecutors but not to humiliate him (cf. 1:17). He asked that the Lord would punish them severely for their apostasy (cf. v. 4; 16:18; 20:12; Ps. 17:1-8).
