John 13:8-14

13:8 Peter said to him, “You will never wash my feet!” Jesus replied, “If I do not wash you, you have no share with me.” 13:9 Simon Peter said to him, “Lord, wash not only my feet, but also my hands and my head!” 13:10 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.” 13:11 (For Jesus knew the one who was going to betray him. For this reason he said, “Not every one of you is clean.”)

13:12 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? 13:13 You call me ‘Teacher’ and ‘Lord,’ and do so correctly, for that is what I am. 13:14 If I then, your Lord and Teacher, have washed your feet, you too ought to wash one another’s feet.
