Luke 2:43 WBT

⁴¹  Now his parents went to Jerusalem every year at the feast of the passover.

⁴²  And when he was twelve years old, they went up to Jerusalem according to the custom of the feast.

⁴³  And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not [of it].

⁴⁴  But they, supposing him to be in the company, went a day's journey; and they sought him among [their] relations and acquaintance.

⁴⁵  And when they found him not, they returned to Jerusalem, seeking him.
