2 Chronicles 35:2-6

2He appointed the priests to their duties and encouraged them in the service of the Lord’s temple. 3He said to the Levites, who instructed all Israel and who had been consecrated to the Lord: “Put the sacred ark in the temple that Solomon son of David king of Israel built. It is not to be carried about on your shoulders. Now serve the Lord your God and his people Israel. 4Prepare yourselves by families in your divisions, according to the instructions written by David king of Israel and by his son Solomon. 5“Stand in the holy place with a group of Levites for each subdivision of the families of your fellow Israelites, the lay people. 6Slaughter the Passover lambs, consecrate yourselves and prepare the lambs for your fellow Israelites, doing what the Lord commanded through Moses.”
