John 6
64 Ref But there are some of you who don't believe." For Jesus knew from the beginning who they were who didn't believe, and who it was who would betray him.
65 Ref He said, "For this cause have I said to you that no one can come to me, unless it is given to him by my Father."
66 Ref At this, many of his disciples went back, and walked no more with him.
67 Ref Jesus said therefore to the twelve, "You don't also want to go away, do you?"
68 Ref Simon Peter answered him, "Lord, to whom would we go? You have the words of eternal life.
69 Ref We have come to believe and know that you are the Christ, the Son of the living God."
70 Ref Jesus answered them, "Didn't I choose you, the twelve, and one of you is a devil?"
71 Ref Now he spoke of Judas, the son of Simon Iscariot, for it was he who would betray him, being one of the twelve.
