John 13:7 ASV

⁵  Then he poureth water into the basin, and began to wash the disciples' feet, and to wipe them with the towel wherewith he was girded.

⁶  So he cometh to Simon Peter. He 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 understand hereafter.

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

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