⁴² When he was twelve years old, they went up to the festival, according to the custom. ⁴³ After the festival was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it. ⁴⁴ Thinking he was in their company, they travelled on for a day. Then they began looking for him among their relatives and friends.
