Luke 2:41-45

41Every year his parents traveled to Jerusalem for the Passover Festival.

42When he was twelve years old, they went up according to the custom of the festival.

43After those days were over, as they were returning, the boy Jesus stayed behind in Jerusalem, but his parents did not know it.

44Assuming he was in the traveling party, they went a day’s journey. Then they began looking for him among their relatives and friends.

45When they did not find him, they returned to Jerusalem to search for him.
