John 13:2-9

2And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon’s son, to betray him;

3Jesus knowing that the Father had given all things into his hands, and that he had come from God, and was going to God;

4He riseth from supper, and laid aside his garments; and took a towel, and girded himself.

5After that he poured water into a basin, and began to wash the disciples’ feet, and to wipe them with the towel with which he was girded.

6Then he cometh to Simon Peter: and Peter saith to him, Lord, dost thou wash my feet?1

7Jesus answered and said to him, What I do thou knowest not now; but thou shalt know after this.

8Peter saith to him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.

9Simon Peter saith to him, Lord, not my feet only, but also my hands and my head.
