John 13:6-11

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.

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

11For he knew who should betray him; therefore said he, Ye are not all clean.
