John 6:66-71

66 (6-67) After this, many of his disciples went back and walked no more with him.

67 (6-68) Then Jesus said to the twelve: Will you also go away?

68 (6-69) And Simon Peter answered him: Lord, to whom shall we go? Thou hast the words of eternal life.

69 (6-70) And we have believed and have known that thou art the Christ, the Son of God.

70 (6-71) Jesus answered them: Have not I chosen you twelve? And one of you is a devil.

71 (6-72) Now he meant Judas Iscariot, the son of Simon: for this same was about to betray him, whereas he was one of the twelve.
