2 Chronicles 23:12-15

12When Athaliah heard the noise of the people running and praising the king, she went into the house of the Lord to the people.

13And when she looked, there was the king standing by his pillar at the entrance, and the captains and the trumpeters beside the king, and all the people of the land rejoicing and blowing trumpets, and the singers with their musical instruments leading in the celebration. And Athaliah tore her clothes and cried, "Treason! Treason!"

14Then Jehoiada the priest brought out the captains who were set over the army, saying to them, "Bring her out between the ranks, and anyone who follows her is to be put to death with the sword." For the priest said, "Do not put her to death in the house of the Lord."

15So they laid hands on her, and she went into the entrance of the horse gate of the king's house, and they put her to death there.
