Luke 2:41-45

The Boy Jesus in the Temple 41Now every year his parents went to Jerusalem for the festival of the Passover.42And when he was twelve years old, they went up as usual for the festival.43When the festival was ended and they started to return, the boy Jesus stayed behind in Jerusalem, but his parents did not know it.44Assuming that he was in the group of travelers, they went a day's journey. Then they started to look for him among their relatives and friends.45When they did not find him, they returned to Jerusalem to search for him.
