John 13:4-10

4rises from supper and lays aside his garments, and having taken a linen towel he girded himself:

5then he pours water into the washhand basin, and began to wash the feet of the disciples, and to wipe them with the linen towel with which he was girded.

6He comes therefore to Simon Peter; and he says to him, Lord, dost thou wash my feet?

7Jesus answered and said to him, What I do thou dost not know now, but thou shalt know hereafter.

8Peter says to him, Thou shalt never wash my feet. Jesus answered him, Unless I wash thee, thou hast not part with me.

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

10Jesus says to him, He that is washed all over needs not to wash save his feet, but is wholly clean; and ye are clean, but not all.
