Luke 2:42-44

Amplified Bible

⁴² And when He was twelve years old, they went up to Jerusalem, according to the custom of the Feast; ⁴³ and as they were returning [to ^[a]Nazareth], after spending the required number of days [at the Feast], the boy Jesus remained behind in Jerusalem. Now His parents did not know this, ⁴⁴ but supposed Him to be in the caravan, and traveled a day’s journey; and [then] they began searching [anxiously] for Him among their relatives and acquaintances.
