2 Chronicles 23:4-7

New International Version

⁴ Now this is what you are to do: A third of you priests and Levites who are going on duty on the Sabbath are to keep watch at the doors, ⁵ a third of you at the royal palace and a third at the Foundation Gate, and all the others are to be in the courtyards of the temple of the Lord. ⁶ No one is to enter the temple of the Lord except the priests and Levites on duty; they may enter because they are consecrated, but all the others are to observe^(A) the Lord’s command not to enter.^{[a] 7} The Levites are to station themselves around the king, each with weapon in hand. Anyone who enters the temple is to be put to death. Stay close to the king wherever he goes.”
