2 Chronicles 23:5-7

Darby Translation

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 except the priests and those of the Levites that do the service; they shall go in, for they are holy; but all the people shall keep the watch of Jehovah.

⁷ And the Levites shall encompass the king round about, every man with his weapons in his hand; and he that comes into the house shall be put to death; and ye shall be with the king when he comes in and when he goes out.
