John 13:8

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.

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.

¹⁰  Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
