Luke 2:42-47

2:42 When he was twelve years old, they went up according to custom. 2:43 But when the feast was over, as they were returning home, the boy Jesus stayed behind in Jerusalem. His parents did not know it, 2:44 but (because they assumed that he was in their group of travelers) they went a day’s journey. Then they began to look for him among their relatives and acquaintances. 2:45 When they did not find him, they returned to Jerusalem to look for him. 2:46 After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. 2:47 And all who heard Jesus were astonished at his understanding and his answers.
