2 Chronicles 23:4-10

4This is the thing that you shall do: of you priests and Levites who come off duty on the Sabbath, one third shall be gatekeepers, 5and one third shall be at the king’s house and one third at the Gate of the Foundation. And all the people shall be in the courts of the house of the LORD. 6Let no one enter the house of the LORD except the priests and ministering Levites. They may enter, for they are holy, but all the people shall keep the charge of the LORD. 7The Levites shall surround the king, each with his weapons in his hand. And whoever enters the house shall be put to death. Be with the king when he comes in and when he goes out.” 8The Levites and all Judah did according to all that Jehoiada the priest commanded, and they each brought his men, who were to go off duty on the Sabbath, with those who were to come on duty on the Sabbath, for Jehoiada the priest did not dismiss the divisions. 9And Jehoiada the priest gave to the captains the spears and the large and small shields that had been King David’s, which were in the house of God. 10And he set all the people as a guard for the king, every man with his weapon in his hand, from the south side of the house to the north side of the house, around the altar and the house.
