John 7:10-15

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?”
