John 7:9- 15 When he had said these words unto them, he abode still in Galilee. But when his brethren were gone up, then went he also up unto the feast, not openly, but as it were in secret. Then the Jews sought him at the feast, and said, Where is he? And there was much murmuring among the people concerning him: for some said, He is a good man: others said, No; but he deceive the people. Howbeit no man spoke openly of him for fear of the Jews. Now about the midst of the feast Jesus went up into the temple, and taught. And the Jews marvelled, saying, How know this man letters, having never learned?
After Jesus’ brothers spoke to Him to go to the feast, He stayed in Galilee for about four days and then went up in the middle of the feast. Any godly man who was seeking to save the lost instead of seeking worldly fame and popularity would want to stay away from the ever changeable mobs. The Rabbinical law required Him to be there the first day, for the performance of many of the rites; but as they were mostly human invention, He would not have thought them proper to attend.
The ‘Jews sought him’ – that is, the rulers of the Jews who were seeking to destroy Him. From the following verses it is clear that many were for Him, but would not openly take a stand for Him for fear of the rulers (vv. 12-13, 30-32, 40-53).
‘How know this man letters, having never learned?’ Most people could not read or write in Bible times, that’s why they gathered at the temple so that a priest could read from the scrolls. Jesus knew their Scriptures, traditions, history and future better than all others combined. (Luke 2:42-47). He had great knowledge and wisdom from God and could read from a young age (Isa. 11:2; 42:1; 50:6; 61:1; Luke 2:40, 52; John 7:16; 8:28, 47; 12:49; 14:10, 24; 17:8).
