John 13:17 Meaning

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

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

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

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

19Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
