2 Kings 11:17-18

17Jehoiada prepared a covenant with the Lord. All the people and the king agreed to serve the Lord as his people. The people also agreed to serve the king faithfully.

18Then people everywhere in the country went to the temple of Baal. They destroyed it. They completely knocked down its altars and idols. They killed Baal's priest, Mattan, in front of Baal's altars. Then Jehoiada the priest put guards to keep the Lord's temple safe.
