John 7:12-18

And there was much murmuring among the multitudes concerning him: some said, He is a good man; others said, Not so, but he leadeth the multitude astray. Yet no man spake openly of him for fear of the Jews. But when it was now the midst of the feast Jesus went up into the temple, and taught. The Jews therefore marvelled, saying, How knoweth this man letters, having never learned? Jesus therefore answered them, and said, My teaching is not mine, but his that sent me. If any man willeth to do his will, he shall know of the teaching, whether it is of God, or whether I speak from myself. He that speaketh from himself seeketh his own glory: but he that seeketh the glory of him that sent him, the same is true, and no unrighteousness is in him.
