2 Chronicles 23:5-7

New American Standard Bible

⁵ and a third shall be at the king’s house, and a third at the Gate of the Foundation; and all the people shall be in the courtyards of the house of the Lord. ⁶ But no one is to enter the house of the Lord except the priests and ^(A)the ministering Levites; they may enter, for they are holy. And all the people are to keep the command of the Lord. ⁷ The Levites will surround the king, each man with his weapons in his hand; and whoever enters the house is to be put to death. Therefore be with the king when he comes in and when he goes out.”
