Then he came to Simon Peter. Peter said to him, "Lord, are you going to wash my feet?"
Jesus replied, "You do not understand what I am doing now, but you will understand after these things."
Peter said to him, "You will never wash my feet!"
Jesus replied, "If I do not wash you, you have no share with me."
Simon Peter said to him, "Lord, wash not only my feet, but also my hands and my head!"
Jesus replied, "The one who has bathed needs only to wash his feet, but is completely clean. And you disciples are clean, but not every one of you." (For Jesus knew the one who was going to betray him. For this reason he said, "Not every one of you is clean.")
So when Jesus had washed their feet and put his outer clothing back on, he took his place at the table again and said to them, "Do you understand what I have done for you? You call me ‘Teacher’ and ‘Lord,’ and do so correctly, for that is what I am. If I then, your Lord and Teacher, have washed your feet, you too ought to wash one another’s feet. For I have given you an example – you should do just as I have done for you. I tell you the solemn truth, the slave is not greater than his master, nor is the one who is sent as a messenger greater than the one who sent him. If you understand these things, you will be blessed if you do them."
