John 13:5-9

5 Next, He poured water into a basin and began to wash His disciples' feet and to dry them with the towel tied around Him.

6 He came to Simon Peter, who asked Him, "Lord, are You going to wash my feet?"

7 Jesus answered him, "What I'm doing you don't understand now, but afterwards you will know."

8 "You will never wash my feet-ever!" Peter said. Jesus replied, "If I don't wash you, you have no part with Me."

9 Simon Peter said to Him, "Lord, not only my feet, but also my hands and my head."
