Now viewing scripture range from the book of 2 Chronicles chapter 23:3 through chapter 23:6...
3 And all the congregation made a covenant with the king in the house of God. And he said unto them, Behold, the king's son shall reign, as the LORD hath said of the sons of David.
4 This is the thing that ye shall do; A third part of you entering on the sabbath, of the priests and of the Levites, shall be porters of the doors;
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.
