João 7

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

15 And the Jews marvelled, 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 be willing to do his will, 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 seekth the glory of him that sent him, the same is true, and there is no unrighteousness in him.
