John 13:12-15Do you understand what I have done to you? You call me Teacher and Lord, and you are right, for so I am. If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. I have given you an example.

Mark 10:42-45You know that those who are considered rulers of the Gentiles lord it over them. It shall not be so among you.
