John 7:16 DBY

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.
