John 7:13-17

Howbeit no man spake openly of him for fear of the Jews.

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

And the Jews marvelled, saying, How knoweth this man letters, having never learned?

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

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