2 Chronicles 23:14-15

14So 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.”

15So 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.
