John 13:25

Verse 25. When Christ had said, one of you is to betray me, Saint Peter whispered with Saint John, by turning to him behind Jesus’s back, and desired him to ask, who this was: now when John had leaned down upon the breast of Jesus, or as the Greek hath it, falling down on the breast of Jesus, as a person may do in a great concern, or fit of grief, he said, Lord, who is it? This posture seems to have been only for that moment of whispering, and to have been different from the posture of eating at table. Witham.
