John 13:6-9

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.” Peter looked at Jesus and said, “You’ll never wash my dirty feet—never!” “But Peter, if you don’t allow me to wash your feet,” Jesus responded, “then you will not be able to share life with me.” So Peter said, “Lord, in that case, don’t just wash my feet, wash my hands and my head too!”
