John 7:10-17

But [afterward], when His brothers had gone up to the feast, He went up too, not publicly [with a caravan], but quietly [because He did not want to be noticed]. So the Jews kept looking for Him at the feast and asking, “Where is He?” There was a lot of whispered discussion and murmuring among the crowds about Him. Some were saying, “He is a good man”; others said, “No, on the contrary, He misleads the people [giving them false ideas].” Yet no one was speaking out openly and freely about Him for fear of [the leaders of] the Jews. When the feast was already half over, Jesus went up into the temple [court] and began to teach. Then the Jews were perplexed. They said, “How did this man become learned [so versed in the Scriptures and theology] without formal training?” Jesus answered them by saying, “My teaching is not My own, but His who sent Me. If anyone is willing to do His will, he will know whether the teaching is of God or whether I speak on My own accord and by My own authority.
