John 13
21 Ref When Jesus had said this, he was troubled in spirit, and testified, "Most assuredly I tell you that one of you will betray me."
22 Ref The disciples looked at one another, perplexed about whom he spoke.
23 Ref One of his disciples, whom Jesus loved, was at the table, leaning against Jesus' breast.
24 Ref Simon Peter therefore beckoned to him, and said to him, "Tell us who it is of whom he speaks."
25 Ref He, leaning back, as he was, on Jesus' breast, asked him, "Lord, who is it?"
26 Ref Jesus therefore answered, "It is he to whom I will give this piece of bread when I have dipped it." So when he had dipped the piece of bread, he gave it to Judas, the son of Simon Iscariot.
