2 Chronicles 23:6-8

New Catholic Bible

⁶ Allow no one to enter the house of the Lord except the priests and the Levites who are on duty. They may enter because they are holy, but all the other people must continue to observe the instructions of the Lord. ⁷ The Levites shall station themselves by surrounding the king on all sides, each one with his weapon drawn, and anyone who tries to enter the temple is to be put to death. They must remain with the king wherever he goes.”

⁸ The Levites and all Judah did everything that the priest Jehoiada had commanded. Each one brought his own men, both those who came on duty on the Sabbath and those who were scheduled to go off duty, since Jehoiada the priest had not dismissed any of the divisions.
