John 13:12-16

Then, when He had washed their feet, and taken His garments and reclined at the table again, He said to them, “Do you know what I have done for you?

You call Me ‘Teacher’ and ‘Lord’; and you are correct, for so I am.

So if I, the Lord and the Teacher, washed your feet, you also ought to wash one another’s feet.

For I gave you an example, so that you also would do just as I did for you.

Truly, truly I say to you, a slave is not greater than his master, nor is one who is sent greater than the one who sent him.
