Luke 2:41-43

21st Century King James Version

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.
