John 13:25

He then lying on Jesus' breast
Being on the couch just before Jesus, with his back to him, he bends backwards, and falling on Jesus' breast, whispers in his ear:

and saith unto him, Lord, who is it?

John 13:25 In-Context

23 There was at table one of His disciples--the one Jesus loved-- reclining with his head on Jesus's bosom.

24 Making a sign therefore to him, Simon Peter said, "Tell us to whom he is referring."

25 So he, having his head on Jesus's bosom, leaned back and asked, "Master, who is it?"

26 "It is the one," answered Jesus, "for whom I shall dip this piece of bread and to whom I shall give it." Accordingly He dipped the piece of bread, and took it and gave it to Judas, the son of the Iscariot Simon.

27 Then, after Judas had received the piece of bread, Satan entered into him. "Lose no time about it," said Jesus to him.
