John 13:12-20

12So after he had washed their feet, and had taken his garments, and was seated again, he said to them, Know ye what I have done to you? 13Ye call me Master and Lord: and ye say well; for so I am. 14If I then, your Lord and Master, have washed your feet; ye also ought to wash one another’s feet. 15For I have given you an example, that ye should do as I have done to you. 16Verily, verily, I say to 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 cometh, that, when it hath come to pass, ye may believe that I am he .1 20Verily, verily, I say to you, He that receiveth whomever I send receiveth me; and he that receiveth me receiveth him that sent me.
