2 Chronicles 35:2-6

Leeser(i) 2 And he placed the priests in their charges, and strengthened them for the service of the house of the Lord. 3 And he said unto the Levites that instructed all Israel, who were holy unto the Lord, Set the holy ark in the house which Solomon the son of David the king of Israel did build; you have not to carry it any more upon your shoulders; now serve the Lord your God, and his people Israel. 4 And prepare yourselves by your family divisions, according to your courses, after the written order of David the king of Israel, and after the written order of Solomon his son; 5 And stand in the holy place according to the divisions of the family divisions of your brethren the sons of the people, and after the division of the families of the Levites; 6 And slaughter the passover-sacrifice, and sanctify yourselves, and prepare it for your brethren, to do according to the word of the Lord by the hand of Moses.
