Luke 2:41-45

41Every year Jesus’ parents went to Jerusalem for the Festival of the Passover.

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

43After the festival was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it.

44Thinking he was in their company, they traveled on for a day. Then they began looking for him among their relatives and friends.

45When they did not find him, they went back to Jerusalem to look for him.
