John 13:18 (KJV)

Ye call me Master and Lord: and ye say well; for so I am.

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

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

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

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

Now I tell you before it come, 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.

When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.

Then the disciples looked one on another, doubting of whom he spake.

Now there was leaning on Jesus' bosom one of his disciples, whom Jesus loved.
