In context
15I have set you an example, so that you may do as I have done for you. 16Very truly I tell you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. 17Now that you know these things, blessed are you if you do them. 18I am not speaking about all of you. I know the ones I have chosen. But the Scripture must be fulfilled: ‘The one who eats my bread has turned his heel against me.’ 19I am telling you now, before it happens, so that when it does happen you may believe that I am he.
