5 After that he pours water into a basin, and began to wash the disciples' feet, and to wipe them with the towel with which he was girded.
6 Then comes he to Simon Peter: and Peter said to him, Lord, do you wash my feet?

8 Peter said to him, You shall never wash my feet. Jesus answered him, If I wash you not, you have no part with me.
