The Boy Jesus in the Temple

⁴¹ Now every year his parents went to Jerusalem for the festival of the Passover. ⁴² And when he was twelve years old, they went up as usual for the festival. ⁴³ When the festival was ended and they started to return, the boy Jesus stayed behind in Jerusalem, but his parents did not know it.
