John 13:18-20

18I speak not of you all. I know those whom I have chosen; but that the scripture might be fulfilled, He that eats bread with me has lifted up his heel against me.

19I tell you [it] now before it happens, that when it happens, ye may believe that I am [he].

20Verily, verily, I say to you, He who receives whomsoever I shall send receives me; and he that receives me receives him who has sent me.
