John 6:65-71

65And he said, Therefore I said to you, that no man can come to me, except it were given to him by my Father. 66From that time many of his disciples went back, and walked no more with him. 67Then said Jesus to the twelve, Will ye also go away? 68Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. 69And we believe and are sure that thou art that Christ, the Son of the living God. 70Jesus answered them, Have not I chosen you twelve, and one of you is a devil? 71He spoke of Judas Iscariot the son of Simon: for it was he that was to betray him, being one of the twelve.
