John 13:6

Jesus, knowing that the Father had given all things into his hands, and that he came from God and was going to God,

arose from supper, and laid aside his outer garments. He took a towel and wrapped a towel around his waist.

Then he poured water into the basin, and began to wash the disciples’ feet and to wipe them with the towel that was wrapped around him.

Jesus answered him, “You don’t know what I am doing now, but you will understand later.”

Peter said to him, “You will never wash my feet!”

Jesus answered him, “If I don’t wash you, you have no part with me.”

Simon Peter said to him, “Lord, not my feet only, but also my hands and my head!”
