John 13:20

I 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.

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

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.
