John 13:3-7

Now Jesus was fully aware that the Father had placed all things under his control, for he had come from God and was about to go back to be with him. So he got up from the meal and took off his outer robe, and took a towel and wrapped it around his waist. Then he poured water into a basin and began to wash the disciples’ dirty feet and dry them with his towel. But when Jesus got to Simon Peter, he objected and said, “I can’t let you wash my dirty feet—you’re my Lord!” Jesus replied, “You don’t understand yet the meaning of what I’m doing, but soon it will be clear to you.”
