John 13:3-5, 14-15

Jesus knew that the Father had given him power over everything and that he had come from God and was going back to God. So during the meal Jesus stood up and took off his outer clothing. Taking a towel, he wrapped it around his waist. Then he poured water into a bowl and began to wash the followers’ feet, drying them with the towel that was wrapped around him.

If I, your Lord and Teacher, have washed your feet, you also should wash each other’s feet. I did this as an example so that you should do as I have done for you.
