13Howbeit no man spake openly of him for fear of the Jews. 14Now about the midst of the feast Jesus went up into the temple, and taught. 15And the Jews marvelled, saying, How knoweth this man letters, having never learned? 16Jesus answered them, and said, My doctrine is not mine, but his that sent me.17If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. 18He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him. 19Did not Moses give you the law, and yet none of you keepeth the law? Why go ye about to kill me?
