2 Chronicles 23:5-7

Revised Standard Version

⁵ and 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. ⁶ Let 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. ⁷ The Levites shall surround the king, each with his weapons in his hand; and whoever enters the house shall be slain. Be with the king when he comes in, and when he goes out.”
