2nd Kings 11:5

2 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;

3 And he was with her hid in the house of Jehovah six years. And Athaliah reigned over the land.

4 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.

5 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;

6 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.

7 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.

8 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.
