2 Chronicles 35:2-6

2He appointed the priests to their duties and encouraged them in the service of the house of the LORD.

3To the Levites who taught all Israel and were holy to the LORD, Josiah said: “Put the holy ark in the temple built by Solomon son of David king of Israel. It is not to be carried around 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 Solomon his son.

5Moreover, stand in the Holy Place by the divisions of the families of your kinsmen the lay people, and by the divisions of the families of the Levites. 6Slaughter the Passover lambs, consecrate yourselves, and make preparations for your fellow countrymen to carry out the word of the LORD given by1 Moses.”
