17 Then Jehoiada made a covenant between the Lord and the king and the people that they would be the Lord 's people. He also made a covenant between the king and the people. 18 And all the people of the land went over to the temple of Baal and tore it down. They demolished the altars and smashed the idols to pieces, and they killed Mattan the priest of Baal in front of the altars. Jehoiada the priest stationed guards at the Temple of the Lord . 19 Then the commanders, the Carite mercenaries, the palace guards, and all the people of the land escorted the king from the Temple of the Lord . They went through the gate of the guards and into the palace, and the king took his seat on the royal throne. 20 So all the people of the land rejoiced, and the city was peaceful because Athaliah had been killed at the king's palace.

Commentary on 2 Kings 11:17-21
(Read 2 Kings 11:17-21)
King and people would cleave most firmly to each other, when both had joined themselves to the Lord. It is well with a people, when all the changes that pass over them help to revive, strengthen, and advance the interests of religion among them. Covenants are of use, both to remind us of, and bind us to, the duties already binding on us. They immediately abolished idolatry; and, pursuant to the covenant with one another, they expressed mutual readiness to help each other. The people rejoiced, and Jerusalem was quiet. The way for people to be joyful and at peace, is to engage fully in the service of God; for the voice of joy and thanksgiving is in the dwellings of the righteous, but there is no peace for the wicked.
