Very truly I tell you, a servant is not greater than his master, nor is a messenger greater than the one who sent him.
In context
14So if I — the Lord and the Teacher — have washed your feet, you also ought to wash one another’s feet. 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.’
