2 Chronicles 23:5-7

King James 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 the Lord.

⁶ But let none come into the house of the Lord, save the priests, and they that minister of the Levites; they shall go in, for they are holy: but all the people shall keep the watch of the Lord.

⁷ And the Levites shall compass the king round about, every man with his weapons in his hand; and whosoever else cometh into the house, he shall be put to death: but be ye with the king when he cometh in, and when he goeth out.
