"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.'" -John 13:12-15
