So He came to Simon Peter. He said to Him, "Lord, do You wash my feet?"
Jesus answered and said to him, "What I do you do not realize now, but you will understand 1hereafter ."
Peter said to Him, "Never shall You wash my feet!" Jesus answered him, "2If I do not wash you, 3you have no part with Me."
Simon Peter said to Him, "Lord, then wash not only my feet, but also my hands and my head."
Jesus said to him, "He who has bathed needs only to wash his feet, but is completely clean; and 4you are clean, but not all of you."
