2 Chronicles 23:12

12. When Athaliah heard the noise of the people running and the shouts of praise to the king, she hurried to the LORD's Temple to see what was happening.
13. And she saw the newly crowned king standing in his place of authority by the pillar at the Temple entrance. The officers and trumpeters were surrounding him, and people from all over the land were rejoicing and blowing trumpets. Singers with musical instruments were leading the people in a great celebration. When Athaliah saw all this, she tore her clothes in despair and shouted, "Treason! Treason!"
14. Then Jehoiada the priest ordered the commanders who were in charge of the troops, "Take her out of the Temple, and kill anyone who tries to rescue her. Do not kill her here in the Temple of the LORD."
15. So they seized her and led her out to the gate where horses enter the palace grounds, and they killed her there.
