John 7

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

15 And the Jews marvelled, saying, How does 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 anyone desires to do his will, he shall know of the doctrine, whether it is of God or whether I speak of myself.

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