2 Chronicles 23:12-15

12When 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.

13When she arrived, she saw the newly crowned king standing in his place of authority by the pillar at the Temple entrance. The commanders 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!”

14Then Jehoiada the priest ordered the commanders who were in charge of the troops, “Take her to the soldiers in front of the Temple, and kill anyone who tries to rescue her.” For the priest had said, “She must not be killed in the Temple of the Lord.”

15So they seized her and led her out to the entrance of the Horse Gate on the palace grounds, and they killed her there.
