2 Chronicles 23:12-15

12When Athaliah heard the noise from the troops, the guards, and those praising the king, she went to the troops in the Lord’s temple.

13As she looked, there was the king standing by his pillar at the entrance. The commanders and the trumpeters were by the king, and all the people of the land were rejoicing and blowing trumpets while the singers with musical instruments were leading the praise. Athaliah tore her clothes and screamed, “Treason! Treason!”

14Then the priest Jehoiada sent out the commanders of hundreds, those in charge of the army, saying, “Take her out between the ranks, and put anyone who follows her to death by the sword,” for the priest had said, “Don’t put her to death in the Lord’s temple.”

15So they arrested her, and she went by the entrance of the Horse Gate to the king’s palace, where they put her to death.
