John 13:19

16 Truly, truly, I say to you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. 17 If you know these things, blessed are you if you do them. 18 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.’ 19 I am telling you this now, before it takes place, that when it does take place you may believe that I am he. 20 Truly, truly, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me.”

21 After saying these things, Jesus was troubled in his spirit, and testified, “Truly, truly, I say to you, one of you will betray me.”

22 The disciples looked at one another, uncertain of whom he spoke.
