12 When he had finished washing their feet, he put on his clothes and returned to his place. "Do you understand what I have done for you?" he asked them. 13 "You call me 'Teacher' and 'Lord,' and rightly so, for that is what I am. 14 Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. 15 I have set you an example that you should do as I have done for you. 16 Very truly I tell you, no servant is greater than his master, nor is a messenger greater than the one who sent him. 17 Now that you know these things, you will be blessed if you do them.
18 "I am not referring to all of you; I know those I have chosen. But this is to fulfill this passage of Scripture: 'He who shared my bread has turnedagainst me.' 19 "I am telling you now before it happens, so that when it does happen you will believe that I am who I am. 20 Very truly I tell you, whoever accepts anyone I send accepts me; and whoever accepts me accepts the one who sent me."
