2 Kings 11:1-7

11When Athaliah the mother of Ahaziah saw that her son was dead, she rose and destroyed all the royal 2offspring. 2But Jehosheba, the daughter of King Joram, sister of Ahaziah, 3took Joash the son of Ahaziah and stole him from among the king’s sons who were being put to death, and placed him and his nurse in the bedroom. So they hid him from Athaliah, and he was not put to death. 3So he was hidden with her in the house of the Lord six years, while Athaliah was reigning over the land.

44Now in the seventh year Jehoiada sent and brought the captains of hundreds of 5the Carites and of the 6guard, and brought them to him in the house of the Lord. Then he made a covenant with them and put them under oath in the house of the Lord, and showed them the king’s son. 5He commanded them, saying, “This is the thing that you shall do: 7one third of you, who come in on the sabbath and keep watch over the king’s house 6(one third also shall be at the gate Sur, and one third at the gate behind the 8guards), 9shall keep watch over the house for defense. 7Two parts of you, even all who go out on the sabbath, shall also keep watch over the house of the Lord for the king.
