2 Chronicles 23:2-6

2They travelled around all the land of Judah. They brought together the Levites from the different cities and the leaders of Israel's clans. They all came to Jerusalem.

3They met together in God's temple to make a promise to the new king. Jehoiada said to them, ‘Here is the king's son. He must become king, as the Lord promised that David's descendants would be.

4This is what you must do: The priests and Levites who come to work on the Sabbath day must make three groups. One group must be guards who watch at the doors of the temple.

5Another group will watch at the king's palace. The third group will stand at the Foundation Gate. All the other men will stand in the yards around the Lord's temple.

6Only the priests and the Levites who have work there on that day may go into the Lord's temple. They may go in because they have made themselves clean to serve God. All the other people must do the jobs that the Lord has given to them.
