68But Simon Peter answered, “Master, to whom would we go? Eternal life is in your teaching;
69and we have learnt to believe and to know that you are the Holy One of God.”
70“Didn't I myself choose you to be the Twelve?” replied Jesus; “and yet, even of you, one is playing the devil's part.”
71He meant Judas, the son of Simon Iscariot, who was about to betray him, though he was one of the Twelve.
