John 13:12-17

When he had finished washing their feet, he put on his clothes and sat down again. Jesus asked, “Do you understand what I have just done for you? You call me ‘Teacher’ and ‘Lord.’ And this is right, because that is what I am. I, your Lord and Teacher, have washed your feet. So you also should wash each other’s feet. I did this as an example for you. So you should do as I have done for you. I tell you the truth. A servant is not greater than his master. A messenger is not greater than the one who sent him. If you know these things, you will be happy if you do them.
