John 13:12-14

King James Version

¹² So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you?

¹³ Ye call me Master and Lord: and ye say well; for so I am.

¹⁴ If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
