John 13:21-30 - Jesus Predicts Judas' Betrayal
21 When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say to you, that one of you will betray me.
22 Then the disciples looked one on another, doubting of whom he spoke. 23 Now there was leaning on Jesus' bosom, one of his disciples, whom Jesus loved. 24 Simon Peter therefore beckoned to him, to ask who it should be of whom he spoke. 25 He then lying on Jesus' breast, saith to him, Lord, who is it?
26 Jesus answered, He it is to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon. 27 And after the sop Satan entered into him. Then said Jesus to him, What thou doest, do quickly.
28 Now no man at the table knew for what intent he spoke this to him. 29 For some of them thought, because Judas had the bag, that Jesus had said to him, Buy those things that we have need of against the feast; or, that he should give something to the poor. 30 He then having received the sop, went immediately out: and it was night.
