John 13:21-30 - Jesus Predicts Judas' Betrayal
21 Jesus having said this, was troubled in spirit, and testified, and said, Verily I say unto you, one of you will betray me.
22 Then the disciples looked one on another, doubting of whom he spake. 23 Now there was lying in the bosom of Jesus, one of the disciples whom Jesus loved. 24 Simon Peter therefore beckoneth to him, to ask who it was of whom he spake. 25 He then, leaning on the breast of Jesus, saith to him, Lord, who is it?
26 Jesus answered, It is he to whom I shall give the sop when I have dipped it. And having dipped the sop, he giveth it to Judas Iscariot, the son of Simon. 27 And after the sop, then Satan entered into him.
28 Then said Jesus to him, What thou dost, do quickly. Now none at the table knew, why he said this to him. 29 But some thought, as Judas had the purse, that Jesus had said to him, Buy what we have need of against the feast, or, Give something to the poor. 30 He then having received the sop, went out immediately. And it was night, when he went out.
