John 13:21-30 - Jesus Predicts Judas' Betrayal
21 When Jesus had spoken these things, he was troubled in spirit, and testified and said: Verily, verily I say to you, that one of you will deliver me up.
22 Then the disciples looked at one another, doubting of whom he spoke. 23 There was reclining on the bosom of Jesus, one of his disciples, whom Jesus loved. 24 Then Simon Peter beckoned to this one, that he should inquire who it was of whom he spoke. 25 And he that was reclining on Jesus breast, said to him: Lord, who is it?
26 Jesus answered: It is he to whom I shall give this morsel after I have dipped it. And when he had dipped the morsel, he gave it to Judas Iscariot, the son of Simon. 27 And after the morsel was given, then Satan entered into him. Then Jesus said to him: What you do, do quickly.
28 But none of those who reclined at table with him knew for what purpose he said this to him. 29 For some thought, because Judas had the purse, that Jesus had said to him: Buy what we need for the feast; or, that he should give something to the poor. 30 Then, on receiving the morsel, he immediately went out; and it was night.
