2 Chronicles 35:1

And he set the priests in their charges, and encouraged them to the service of the house of the LORD,

And said unto the Levites that taught all Israel, which were holy unto the LORD, Put the holy ark in the house which Solomon the son of David king of Israel did build; it shall not be a burden upon your shoulders: serve now the LORD your God, and his people Israel,

And prepare yourselves by the houses of your fathers, after your courses, according to the writing of David king of Israel, and according to the writing of Solomon his son.

And stand in the holy place according to the divisions of the families of the fathers of your brethren the people, and after the division of the families of the Levites.
