2 Chronicles 23:4-6

Lexham English Bible

⁴ This is the thing that you must do: one third of you priests and Levites coming off duty on the Sabbath^[a] shall be gatekeepers at the entrances, ⁵ and one third at the house of the king, and one third at the Gate of the Foundation. And all the people shall be in the courtyards of the house of Yahweh. ⁶ Let no one enter into the house of Yahweh except the priests and the ministering Levites. They themselves may enter, for they are holy, but all the people shall keep the requirements of Yahweh.
