Jesus said to him, "One who has bathed does not need to wash, except for the feet, but is entirely clean. And you are clean, though not all of you."
For he knew who was to betray him; for this reason he said, "Not all of you are clean."
After he had washed their feet, had put on his robe, and had returned to the table, he said to them, "Do you know what I have done to you?
You call me Teacher and Lord—and you are right, for that is what I am.
So if I, your Lord and Teacher, have washed your feet, you also ought to wash one another's feet.
For I have set you an example, that you also should do as I have done to you.
Very truly, I tell you, servants are not greater than their master, nor are messengers greater than the one who sent them.
If you know these things, you are blessed if you do them.
I am not speaking of all of you; I know whom I have chosen. But it is to fulfill the scripture, "The one who ate my bread has lifted his heel against me.'
I tell you this now, before it occurs, so that when it does occur, you may believe that I am he.
