Luke 2:43-45

World English Bible

⁴³ and when they had fulfilled the days, as they were returning, the boy Jesus stayed behind in Jerusalem. Joseph and his mother didn’t know it, ⁴⁴ but supposing him to be in the company, they went a day’s journey, and they looked for him among their relatives and acquaintances. ⁴⁵ When they didn’t find him, they returned to Jerusalem, looking for him.
