John 13:12-14

Young's Literal Translation

¹² When, therefore, he washed their feet, and took his garments, having reclined (at meat) again, he said to them, `Do ye know what I have done to you?

¹³ ye call me, The Teacher and The Lord, and ye say well, for I am;

¹⁴ if then I did wash your feet -- the Lord and the Teacher -- ye also ought to wash one another's feet.
