John 13:12-17

When Jesus had washed their feet and put on His robe, He reclined again and said to them, “Do you know what I have done for you? You call Me Teacher and Lord. This is well said, for I am. So if I, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. For I have given you an example that you also should do just as I have done for you. “I assure you: A slave is not greater than his master, and a messenger is not greater than the one who sent him. If you know these things, you are blessed if you do them.
