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 was come from God, and went to God;

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

5After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.

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

7Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.

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

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