John 13:6

2 The evening meal was underway, and the devil had already put into the heart of Judas, the son of Simon Iscariot, to betray Jesus.

3 Jesus knew that the Father had delivered all things into His hands, and that He had come from God and was returning to God.

4 So He got up from the supper, laid aside His outer garments, and wrapped a towel around His waist.

5 After that, He poured water into a basin and began to wash the disciples’ feet and dry them with the towel that was around Him.

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

7 Jesus replied, “You do not realize now what I am doing, but later you will understand.”

8 “Never shall You wash my feet!” Peter told Him. Jesus answered, “Unless I wash you, you have no part with Me.”

9 “Then, Lord,” Simon Peter replied, “not only my feet, but my hands and my head as well!”

10 Jesus told him, “Whoever has already bathed needs only to wash his feet, and he will be completely clean. And you are clean, though not all of you.”
