This story is narrated in John 7.  In this episode, Jesus’ own biological brothers urge him to attend the Feast of Tabernacles which will be held in Jerusalem.  At the time, Jesus was in the Galilee area in the north.  He had been facing hostility in the south.  Jesus tells his brothers, “No.”  Later, Jesus goes to the Feast.  At first, he does not nothing openly.  Later, he shows up in the temple and teaches.  This prompts the people to express their opinions of Jesus, which ranged from those who thought he was a good man and those who thought he was leading the people astray.  Though the people in the temple were surprised that Jesus seemed so educated, he argued that had nothing to do with formal education.  Instead, he seemed literate, so to speak, because of the One who had sent him.
