2 Kings 11:12-16

12Then he brought out the king's son and put the crown on him and gave him the testimony. And they proclaimed him king and anointed him, and they clapped their hands and said, "Long live the king!"

13When Athaliah heard the noise of the guard and of the people, she went into the house of the Lord to the people.

14And when she looked, there was the king standing by the pillar, according to the custom, and the captains and the trumpeters beside the king, and all the people of the land rejoicing and blowing trumpets. And Athaliah tore her clothes and cried, "Treason! Treason!"

15Then Jehoiada the priest commanded the captains who were set over the army, "Bring her out between the ranks, and put to death with the sword anyone who follows her." For the priest said, "Let her not be put to death in the house of the Lord."

16So they laid hands on her; and she went through the horses' entrance to the king's house, and there she was put to death.
