2 Chronicles 23:5-7

American Standard Version

⁵ and a third part shall be at the king’s house; and a third part at the gate of the foundation: and all the people shall be in the courts of the house of Jehovah. ⁶ But let none come into the house of Jehovah, save the priests, and they that minister of the Levites; they shall come in, for they are holy: but all the people shall keep the charge of Jehovah. ⁷ And the Levites shall compass the king round about, every man with his weapons in his hand; and whosoever cometh into the house, let him be slain: and be ye with the king when he cometh in, and when he goeth out.
