2 Chronicles 35:2-6

2He appointed the priests to their responsibilities and encouraged them to serve in the Lord’s temple.

3He said to the Levites who taught all Israel the holy things of the Lord, “Put the holy ark in the temple built by Solomon son of David king of Israel. Since you do not have to carry it on your shoulders, now serve the Lord your God and his people Israel.

4“Organize your ancestral families by your divisions according to the written instruction of King David of Israel and that of his son Solomon.

5Serve in the holy place by the groupings of the ancestral families for your brothers, the lay people, and according to the division of the Levites by family.

6Slaughter the Passover lambs, consecrate yourselves, and make preparations for your brothers to carry out the word of the Lord through Moses.”
