“Know you what I have done to you? You call me, Teacher, and, Lord: and you say well; for so I am. If I then, the Lord and the 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 as I have done to you. Verily, verily, I say unto you, A servant is not greater than his lord; neither one that is sent greater than he that sent him. If you know these things, blessed are you if you do them.”
