Luke 2:41-43, 46-47

Every year Jesus’ parents went to Jerusalem for the Festival of the Passover. When he was twelve years old, they went up to the festival, according to the custom. After the festival was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it.

After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. Everyone who heard him was amazed at his understanding and his answers.
