2 Chronicles 23:11

7 The Levites must surround the king with weapons in hand, and anyone who enters the temple must be put to death. You must stay close to the king wherever he goes.”

8 So the Levites and all Judah did everything that Jehoiada the priest had ordered. Each of them took his men—those coming on duty on the Sabbath and those going off duty—for Jehoiada the priest had not released any of the divisions.

9 Then Jehoiada the priest gave to the commanders of hundreds the spears and the large and small shields of King David that were in the house of God.

10 He stationed all the troops, with their weapons in hand, surrounding the king by the altar and the temple, from the south side to the north side of the temple.

11 Then Jehoiada and his sons brought out the king’s son, put the crown on him, presented him with the Testimony, and proclaimed him king. They anointed him and shouted, “Long live the king!”

12 When Athaliah heard the noise of the people running and cheering the king, she went out to them in the house of the LORD.

13 And she looked out and saw the king standing by his pillar at the entrance. The officers and trumpeters were beside the king, and all the people of the land were rejoicing and blowing trumpets, while the singers with musical instruments were leading the praises. Then Athaliah tore her clothes and screamed, “Treason, treason!”

14 And Jehoiada the priest sent out the commanders of hundreds in charge of the army, saying, “Bring her out between the ranks, and put to the sword anyone who follows her.” For the priest had said, “She must not be put to death in the house of the LORD.”

15 So they seized Athaliah as she reached the entrance of the Horse Gate to the palace grounds, and there they put her to death.
