John 13:8-11

8“No,” said Peter, “you shall never wash my feet.” Jesus answered, “Unless I wash you, you have no part with me.”

9“Then, Lord,” Simon Peter replied, “not just my feet but my hands and my head as well!” 10Jesus answered, “Those who have had a bath need only to wash their feet; their whole body is clean. And you are clean, though not every one of you.”

11For he knew who was going to betray him, and that was why he said not every one was clean.
