John 13:21-30 - Jesus Predicts Judas' Betrayal
21 [When he] had said these [things], Jesus was troubled in spirit and testified and said, "Truly, truly I say to you that one of you will betray me."
22 The disciples began looking at one another, uncertain about whom he was speaking. 23 One of his disciples--the one whom Jesus loved--was reclining {close beside} Jesus. 24 So Simon Peter gestured for this one to inquire who it was about whom he was speaking. 25 He leaned back accordingly against Jesus' chest [and] said to him, "Lord, who is it?"
26 Jesus replied, "It is he to whom I dip the piece of bread and give [it] to him." Then [after] dipping the piece of bread, he gave [it] to Judas [son] of Simon Iscariot. 27 And after the piece of bread, then Satan entered into him. Then Jesus said to him, "What you are doing, do quickly!"
28 (Now no one of those reclining at table knew for what [reason] he said this to him. 29 For some were thinking because Judas had the money box, Jesus was telling him, "Purchase {what we need} for the feast," or that he should give something to the poor.) 30 So [after he] had taken the piece of bread, he went out immediately. And it was night.
