John 13:3-7

Jesus knew that the Father had given him authority over everything and that he had come from God and would return to God. So he got up from the table, took off his robe, wrapped a towel around his waist, and poured water into a basin. Then he began to wash the disciples’ feet, drying them with the towel he had around him. When Jesus came to Simon Peter, Peter said to him, “Lord, are you going to wash my feet?” Jesus replied, “You don’t understand now what I am doing, but someday you will.”
