John 13:12-15

12When therefore he had washed their feet, and taken his garments, having sat down again, he said to them, Do ye know what I have done to you?

13Ye call me the Teacher and the Lord, and ye say well, for I am [so].

14If I therefore, the Lord and the Teacher, have washed your feet, ye also ought to wash one another's feet;

15for I have given you an example that, as I have done to you, ye should do also.
