Jesus had spoken only briefly about His betrayal until now (cf. 6:70; 13:10, 18). Now He gave the Twelve more specific information.
13:21-22 The prospect of His imminent betrayal and death upset Jesus visibly (Gr. etarachthe, cf. 11:33; 12:27). Clearly the Twelve had not understood that one of them would betray Him (cf. Matt. 26:21-22; Mark 14:18-19; Luke 22:21-23). Judas had been a successful hypocrite. Jesus' solemn announcement now forced Judas to act quickly or to repent.
13:23 This is John's first reference to himself as the beloved disciple (cf. 19:26-27; 20:2-9; 21:1, 20-25; Mark 14:17). He enjoyed an intimate relationship to Jesus similar to the one Jesus enjoyed with His Father (cf. 1:18). John was not claiming that Jesus loved him more than the other disciples by describing himself this way. Rather the description reveals his appreciation for God's grace in loving him as He did. He focused the reader's attention on Jesus more forcefully by omitting his own name.
"Like the other John at the very beginning of the Gospel, the first witness to Jesus, he is only a voice. The identity of the speaker does not matter: what matters is the witness that he gives."439
"It was customary to sit at most meals. Reclining at table, a hellenistic custom, was reserved for special meals. When first introduced into the Jewish world, it was probably a sign of extreme decadence (Am. 6:4-7), but by New Testament times it was normal at important banquets and feasts, and therefore was virtually required at the Passover celebration, almost as a mark of unhurried celebration and freedom, in self-conscious contrast with the haste with which the first Passover was eaten on the night of the exodus (Ex. 12:11; cf. B. Pesahim108a; NewDocs1. § 1; 2. § 26). In short, the posture of Jesus and his men is a small indicator that they were in fact eating the Passover meal . . ."440
13:24-25 Evidently Peter was somewhere across the table from Jesus. He was unable to ask Jesus privately to identify the betrayer. John must have reclined on his left elbow immediately to Jesus' right. By leaning back against Jesus' chest John could have whispered his request quietly. Leonardo da Vinci's The Last Supperis a beautiful painting, but it does not represent the table arrangement as it would have existed in the upper room.
13:26 Jesus identified Judas as the betrayer to John. The morsel or piece of bread (Gr. psomion) was probably a piece of unleavened bread that Jesus had dipped into the bowl of paschal stew. Passover participants normally did this early in the meal. The host would sometimes do this and pass a morsel of bread and meat to an honored guest. Jesus did this to Judas.
Judas must have sat near enough to Jesus for Jesus to do this conveniently. Possibly Judas reclined to Jesus' immediate left. If he did, this would have put him in the place of the honored guest immediately to the host's left.
Perhaps it was the apparently high honor that Jesus bestowed on Judas by extending the morsel to him that counteracted what Jesus had just said to John about the betrayer. Could Jesus really mean that the disciple who was the guest of honor would betray Him? This apparent contradiction may explain John's lack of response to Jesus' words to him about the betrayer.
Jesus' act of friendship to Judas triggered Judas' betrayal of Jesus' friendship.441This was Jesus' final gesture of supreme love for Judas (cf. v. 1).
Only Matthew recorded Judas' hypocritical question, "Surely it is not I, Rabbi?"and Jesus' reply, "You have said it yourself"(Matt. 26:25).
13:27 Judas accepted Jesus' food but not His love. Instead of repenting Judas continued to resist. This resistance opened the way for Satan to take control of him in a stronger way than he had done previously (cf. 3:16-19). Evidently Satan himself rather than just one of his demonic assistants gained control of Judas.442
Undoubtedly Satan took control because he wanted to destroy Jesus. We should not conclude that Satan necessarily or directly controls everyone who opposes God's will. Judas' case was particularly significant in view of the situation. The text does not use the term "possession"to describe Satan's relationship to Judas, but certainly his influence on the traitor must have been very strong.
The opportunity for repentance had passed due to persistence in unbelief. Therefore Jesus did not appeal to Judas to change his mind but to get on with his evil work "quickly"(Gr. tacheion). Jesus' hour had come, and it was essential that Judas not thwart God's plan by delaying.
13:28 No one present knew what Jesus meant when He told Judas to do what he had to do quickly. John must have known that Judas was the betrayer, but even he did not know that Jesus was referring here to Judas' arrangements to betray Him.
"There is nothing in the narrative to show that Jesus meant that betrayal was imminent. From all that has been said so far it may well have been far in the future."443
13:29 The fact that Judas was the treasurer of the Twelve shows that the other disciples trusted him implicitly. He was a consummate hypocrite. Jesus' trust of him shows the Savior's grace.
The feast in view (v. 29) must have been the feast of Unleavened Bread that followed Passover immediately since Jesus and the Twelve were then celebrating the Passover. Giving alms to the poor was a common practice in Jerusalem on Passover evening.444
13:30 Judas obeyed Jesus' command (v. 27) and left the upper room immediately. He missed most of the meal including the institution of the Lord's Supper. John's reference to it being night would be redundant if all he wanted to do was give a time reference. In view of his light and darkness motif, it seems that he wanted to point out the spiritual significance of Judas' departure both for Judas and for Jesus (cf. Luke 22:53; John 1:4-5; et al.).
"As the Light of the world was about to depart and return to the Father, the darkness had come at last (cf. Luke 22:53). Again the contrast in imagery is clear. For John, Jesus is the Light of the world, and those who believe in Him come to the light and walk in the light. At the opposite extreme is Judas Iscariot, who rejected Jesus, cast in his lot with the powers of darkness, departed into the darkness, and was swallowed up by it."445
