John 13:15 YLT

¹³  ye call me, The Teacher and The Lord, and ye say well, for I am;

¹⁴  if then I did wash your feet -- the Lord and the Teacher -- ye also ought to wash one another's feet.

¹⁵  'For an example I gave to you, that, according as I did to you, ye also may do;

¹⁶  verily, verily, I say to you, a servant is not greater than his lord, nor an apostle greater than he who sent him;

¹⁷  if these things ye have known, happy are ye, if ye may do them;
