2 Chronicles 23:12-15

When Athaliah heard the sound of the people running and praising the king, she went into the house of the LORD to [see what] the people [were doing]. She looked, and there was the [young] king, standing by his pillar at the entrance, and the captains and the trumpeters were beside him. And all the people of the land were rejoicing and blowing trumpets, and the singers with their musical instruments were directing the [singing of] praise. Then Athaliah tore her clothes and cried, “Treason! Treason!” So Jehoiada the priest brought out the captains of hundreds who were appointed over the army and said to them, “Bring her out between the ranks [of soldiers]; and whoever follows her shall be put to death with the sword.” For the priest had said, “Do not let her be put to death in the temple of the LORD.” So they seized Athaliah, and when she arrived at the entrance of the Horse Gate of the king’s house (palace), they put her to death there.
