John 6:66-71

66From this time many of his disciples turned back and no longer followed him.

67“You do not want to leave too, do you?” Jesus asked the Twelve. 68Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life.

69We have come to believe and to know that you are the Holy One of God.” 70Then Jesus replied, “Have I not chosen you, the Twelve? Yet one of you is a devil!” 71(He meant Judas, the son of Simon Iscariot, who, though one of the Twelve, was later to betray him.)
