John 13:14-16
13:14 If I then, your Lord and Teacher, have washed your feet, you too ought to wash one another’s feet.
13:15 For I have given you an example – you should do just as I have done for you.
13:16 I tell you the solemn truth, the slave is not greater than his master, nor is the one who is sent as a messenger greater than the one who sent him.
John 13:34
