John 13:24

22The disciples looked at one another, perplexed about whom he spoke.

23One of his disciples, whom Jesus loved, was at the table, leaning against Jesus’ chest.

24Simon Peter therefore beckoned to him, and said to him, “Tell us who it is of whom he speaks.”

25He, leaning back, as he was, on Jesus’ chest, asked him, “Lord, who is it?”

26Jesus 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.
