John 6:66-71

66 Thereupon many of His disciples left Him and went away, and no longer associated with Him.

67 Jesus therefore appealed to the Twelve. "Will you go also?" He asked.

68 "Master," replied Simon Peter, "to whom shall we go? Your teachings tell us of the Life of the Ages.

69 And we have come to believe and know that *you* are indeed the Holy One of God."

70 "Did not I choose you--the Twelve?" said Jesus, "and even of you one is a devil."

71 He alluded to Judas, the son of Simon the Iscariot. For he it was who, though one of the Twelve, was afterwards to betray Him.
