Luke 2:43-45

American Standard Version

⁴³ and when they had fulfilled the days, as they were returning, the boy Jesus tarried behind in Jerusalem; and his parents knew it not; ⁴⁴ but supposing him to be in the company, they went a day’s journey; and they sought for him among their kinsfolk and acquaintance: ⁴⁵ and when they found him not, they returned to Jerusalem, seeking for him.
