John 13:14-16

AKJV(i) 14 If I then, your Lord and Master, have washed your feet; you also ought to wash one another's feet. 15 For I have given you an example, that you should do as I have done to you. 16 Truly, truly, I say to you, The servant is not greater than his lord; neither he that is sent greater than he that sent him.
