John 6:66-71

66 At this, many of his talmidim went back, and walked no more with him.

67 Yeshua said therefore to the twelve, "You don't also want to go away, do you?"

68 Shim`on Kefa answered him, "Lord, to whom would we go? You have the words of eternal life.

69 We have come to believe and know that you are the Messiah, the Son of the living God."

70 He answered them, "Didn't I choose you, the twelve, and one of you is a devil?"

71 Now he spoke of Yehudah, the son of Shim`on Ish-K'riot, for it was he who would betray him, being one of the twelve.
