14 But when it was now the middle of the feast, Jesus went up into the temple and taught.

15 The Jews therefore wondered, saying, How knows this {man} letters, having never learned?

16 Jesus therefore answered them and said, My doctrine is not mine, but {that} of him that has sent me.

17 If any one desire to practise his will, he shall know concerning the doctrine, whether it is of God, or {that} I speak from myself.

18 He that speaks from himself seeks his own glory; but he that seeks the glory of him that has sent him, he is true, and unrighteousness is not in him.
