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.
