John 13:8-11

Peter said to Him, “You will never wash my feet!” Jesus answered, “Unless I wash you, you have no part with Me [we can have nothing to do with each other].” Simon Peter said to Him, “Lord, [in that case, wash] not only my feet, but also my hands and my head!” Jesus said to him, “Anyone who has bathed needs only to wash his feet, and is completely clean. And you [My disciples] are clean, but not all of you.” For He knew who was going to betray Him; for that reason He said, “Not all of you are clean.”
