15 For I have given you an example, that just as I have done for you, you also do.
16 Truly, truly I say to you, a slave is not greater than his master, nor a messenger greater than the one who sent him.
17 If you understand these things, you are blessed if you do them.
18 “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.’
19 From now on I am telling you before it happens, in order that when it happens you may believe that I am he.
20 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.”
21 When he had said these things, Jesus was troubled in spirit and testified and said, “Truly, truly I say to you that one of you will betray me.”
