(For he knew the one who would betray him; because of this he said, "Not all [of you] are clean.")
So when he had washed their feet and taken his outer clothing and reclined at table again, he said to them, "Do you understand what I have done for you?
You call me 'Teacher' and 'Lord,' and you speak correctly, for I am.
If then I--[your]a Lord and Teacher--wash your feet, you also ought to wash one another's feet.
For I have given you an example, that just as I have done for you, you also do.
Truly, truly I say to you, a slave is not greater than his master, nor a messenger greater than the one who sent him.
If you understand these [things], you are blessed if you do them.
"I am not speaking about all of you. I know whom I have chosen, but in order that the scripture would be fulfilled, 'The one who eats my bread has lifted up his heel against me.'b19
From now [on] I am telling you before [it] happens, in order that when [it] happens you may believe that I am [he].c20
Truly, truly I say to you, the one who receives anyone I send receives me, and the one who receives me receives the one who sent me."
