2 Chronicles 23:12-15

12And Athaliah heard the noise of the people running and praising the king, and she came to the people into the house of Jehovah.

13And she looked, and behold, the king stood on his dais at the entrance, and the princes and the trumpets were by the king; and all the people of the land rejoiced, and blew with trumpets; and the singers [were there] with the instruments of music, and such as taught to sing praise. And Athaliah rent her garments, and said, Conspiracy! Conspiracy!

14And Jehoiada the priest brought out the captains of the hundreds that were set over the host, and said to them, Lead her forth without the ranks; and whosoever follows her, let him be slain with the sword; for the priest said, Ye shall not put her to death in the house of Jehovah.

15And they made way for her, and she went through the entrance of the horse-gate into the king's house, and they put her to death there.
