John 13:12-20

So when he had washed their feet, and taken his garments, and sat down again, he said unto them, Know ye what I have done to you? Ye call me, Teacher, and, Lord: and ye say well; for so I am. If I then, the Lord and the Teacher, have washed your feet, ye also ought to wash one another’s feet. For I have given you an example, that ye also should do as I have done to you. 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. If ye know these things, blessed are ye if ye do them. 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. From henceforth I tell you before it come to pass, that, when it is come to pass, ye may believe that I am he. Verily, verily, I say unto you, He that receiveth whomsoever I send receiveth me; and he that receiveth me receiveth him that sent me.
