12 And there was a lot of grumbling concerning him among the crowds; some were saying, “He is a good man,” but others were saying, “No, but he deceives the crowd.”
13 However, no one was speaking openly about him for fear of the Jews.
14 Now when the feast was already half over, Jesus went to the temple courts and began to teach.
15 Then the Jews were astonished, saying, “How does this man possess knowledge, because he has not been taught?”
16 So Jesus answered them and said, “My teaching is not mine, but is from the one who sent me.
17 If anyone wants to do his will, he will know about my teaching, whether it is from God or I am speaking from myself.
18 The one who speaks from himself seeks his own glory. But the one who seeks the glory of the one who sent him—this one is true, and there is no unrighteousness in him.
