John 13:5

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

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

⁵  After 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.

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

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