2 Kings 11:17-18

Jehoiada then made a covenant between the LORD and the king and people that they would be the LORD’s people. He also made a covenant between the king and the people. All the people of the land went to the temple of Baal and tore it down. They smashed the altars and idols to pieces and killed Mattan the priest of Baal in front of the altars. Then Jehoiada the priest posted guards at the temple of the LORD.
