⁵ Then he poured water into a basin and began to wash the disciples’ feet and to wipe them with the towel that was tied around him. ⁶ He came to Simon Peter, who said to him, ‘Lord, are you going to wash my feet?’ ⁷ Jesus answered, ‘You do not know now what I am doing, but later you will understand.’
