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

15 And the Jews marveled, saying, How knows this man letters, having never learned?

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

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

18 He that speaks of himself seeks his own glory: but he that seeks his glory that sent him, the same is true, and no unrighteousness is in him.
