Luke 2:41-43

New Matthew Bible

⁴¹ Now his father and mother 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 the days had come to an end, as they turned back for home, the child Jesus remained still in Jerusalem, unbeknownst to his father and mother.
