16Very truly, I tell you, servants are not greater than their master, nor are messengers greater than the one who sent them. 17If you know these things, you are blessed if you do them. 18I am not speaking of all of you; I know whom I have chosen. But it is to fulfil the scripture, “The one who ate my bread has lifted his heel against me.” 19I tell you this now, before it occurs, so that when it does occur, you may believe that I am he.20Very truly, I tell you, whoever receives one whom I send receives me; and whoever receives me receives him who sent me.’
