2 Chronicles 23:4-6

Holman Christian Standard Bible

⁴ This is what you are to do: a third of you, priests and Levites who are coming on duty on the Sabbath,^(A) are to be gatekeepers. ⁵ A third are to be at the king’s palace, and a third are to be at the Foundation Gate, and all the troops will be in the courtyards of the Lord’s temple. ⁶ No one is to enter the Lord’s temple but the priests and those Levites who serve;^(B) they may enter because they are holy, but all the people are to obey the requirement of the Lord.
