John 13:18-21

I am not speaking of all of you; I know whom I have chosen. But the Scripture will be fulfilled,‘He who ate my bread has lifted his heel against me.’ I am telling you this now, before it takes place, that when it does take place you may believe that I am he. Truly, truly, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me.” After saying these things, Jesus was troubled in his spirit, and testified, “Truly, truly, I say to you, one of you will betray me.”
