2 Chronicles 23:15

11 Then Jehoiada and his sons brought out the king’s son, put the crown on him, presented him with the Testimony, and proclaimed him king. They anointed him and shouted, “Long live the king!”

12 When Athaliah heard the noise of the people running and cheering the king, she went out to them in the house of the LORD.

13 And she looked out and saw the king standing by his pillar at the entrance. The officers and trumpeters were beside the king, and all the people of the land were rejoicing and blowing trumpets, while the singers with musical instruments were leading the praises. Then Athaliah tore her clothes and screamed, “Treason, treason!”

14 And Jehoiada the priest sent out the commanders of hundreds in charge of the army, saying, “Bring her out between the ranks, and put to the sword anyone who follows her.” For the priest had said, “She must not be put to death in the house of the LORD.”

15 So they seized Athaliah as she reached the entrance of the Horse Gate to the palace grounds, and there they put her to death.

16 Then Jehoiada made a covenant between himself and the king and the people that they would be the LORD’s people.

17 So all the people 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.

18 Moreover, Jehoiada put the oversight of the house of the LORD into the hands of the Levitical priests, whom David had appointed over the house of the LORD, to offer burnt offerings to the LORD as is written in the Law of Moses, with rejoicing and song, as ordained by David.

19 He stationed gatekeepers at the gates of the house of the LORD, so that nothing unclean could enter for any reason.
