John 13:1-6

Now before the feast of the passover, Jesus knowing that his hour was come that he should depart out of this world unto the Father, having loved his own that were in the world, he loved them unto the end. And during supper, the devil having already put into the heart of Judas Iscariot, Simon’s son, to betray him, Jesus, knowing that the Father had given all things into his hands, and that he came forth from God, and goeth unto God, riseth from supper, and layeth aside his garments; and he took a towel, and girded himself. Then he poureth water into the basin, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded. So he cometh to Simon Peter. He saith unto him, Lord, dost thou wash my feet?
