John 13:14

For he knew him who would betray him; therefore he said, “You are not all clean.”

So when he had washed their feet, put his outer garment back on, and sat down again, he said to them, “Do you know what I have done to you?

You call me, ‘Teacher’ and ‘Lord.’ You say so correctly, for so I am.

For I have given you an example, that you should also do as I have done to you.

Most certainly I tell you, a servant is not greater than his lord, neither is one who is sent greater than he who sent him.

If you know these things, blessed are you if you do them.
