John 13:8-11
13:8 Peter said to him, “You will never wash my feet!” Jesus replied, “If I do not wash you, you have no share with me.”
13:9 Simon Peter said to him, “Lord, wash not only my feet, but also my hands and my head!”
13:10 Jesus replied, “The one who has bathed needs only to wash his feet, but is completely clean. And you disciples are clean, but not every one of you.”
13:11 (For Jesus knew the one who was going to betray him. For this reason he said, “Not every one of you is clean.”)
