John 13:12-15

12So after He had washed their feet and put His robe back on and reclined again, He said to them, “Do you understand what I have done for you?

13You call Me ‘Teacher’ and ‘Master’—and rightly you say, for I am.

14So if I, your Master and Teacher, have washed your feet, you also ought to wash each other’s feet.

15I have given you an example—you should do for each other what I have done for you.
