14 But when it was now the middle of the feast, Jesus went up into the temple and taught. 15 The Jews therefore marveled, saying, "How does this man know letters, having never been educated?"

16 Jesus therefore answered them, "My teaching is not mine, but his who sent me. 17 If anyone desires to do his will, he will know about the teaching, whether it is from God or if I am speaking from myself. 18 He who speaks from himself seeks his own glory, but he who seeks the glory of him who sent him is true, and no unrighteousness is in him.
