John 13:16 ASV

¹⁴  If I then, the Lord and the Teacher, have washed your feet, ye also ought to wash one another's feet.

¹⁵  For I have given you an example, that ye also should do as I have done to you.

¹⁶  Verily, verily, I say unto you, a servant is not greater than his lord; neither one that is sent greater than he that sent him.

¹⁷  If ye know these things, blessed are ye if ye do them.

¹⁸  I speak not of you all: I know whom I have chosen: but that the scripture may be fulfilled: He that eateth my bread lifted up his heel against me.
