14 Now about the midst of the feast, Jesus went up into the temple, and taught.

15 And the Jews wondered, saying: How doth this man know letters, having never learned?

16 Jesus answered them, and said: My doctrine is not mine, but his that sent me.

17 If any man do the will of him; he shall know of the doctrine, whether it be of God, or whether I speak of myself.

18 He that speaketh of himself, seeketh his own glory: but he that seeketh the glory of him that sent him, he is true, and there is no injustice in him.
