John 13:12-15

12When he had finished washing their feet, he put on his clothes and returned to his place. “Do you understand what I have done for you?” he asked them.

13“You call me ‘Teacher’ and ‘Lord,’ and rightly so, for that is what I am.

14Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet.

15I have set you an example that you should do as I have done for you.
