John 13:22-26

Then the disciples looked at one another, perplexed about whom He spoke. Now there was leaning on Jesus’ bosom one of His disciples, whom Jesus loved. Simon Peter therefore motioned to him to ask who it was of whom He spoke. Then, leaning back on Jesus’ breast, he said to Him, “Lord, who is it?” Jesus answered, “It is he to whom I shall give a piece of bread when I have dipped it.” And having dipped the bread, He gave it to Judas Iscariot, the son of Simon.
