2 Kings 11:1-8

Now when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal. But Jehosheba, the daughter of king Joram, sister of Ahaziah, took Joash the son of Ahaziah, and stole him away from among the king’s sons that were slain, even him and his nurse, and put them in the bedchamber; and they hid him from Athaliah, so that he was not slain; And he was with her hid in the house of Jehovah six years. And Athaliah reigned over the land. And in the seventh year Jehoiada sent and fetched the captains over hundreds of the Carites and of the guard, and brought them to him into the house of Jehovah; and he made a covenant with them, and took an oath of them in the house of Jehovah, and showed them the king’s son. And he commanded them, saying, This is the thing that ye shall do: a third part of you, that come in on the sabbath, shall be keepers of the watch of the king’s house; and a third part shall be at the gate Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, and be a barrier. And the two companies of you, even all that go forth on the sabbath, shall keep the watch of the house of Jehovah about the king. And ye shall compass the king round about, every man with his weapons in his hand; and he that cometh within the ranks, let him be slain: and be ye with the king when he goeth out, and when he cometh in.
