John 13:23-26

23One of his disciples, whom Jesus loved, was reclining at table at Jesus' side,

24so Simon Peter motioned to him to ask Jesus of whom he was speaking.

25So that disciple, leaning back against Jesus, said to him, "Lord, who is it?"

26Jesus answered, "It is he to whom I will give this morsel of bread when I have dipped it." So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot.
