2 Chronicles 35:3-4

3Then he said to the Levites who taught all Israel, who were holy to the Lord: “Put the holy ark in the house which Solomon the son of David, king of Israel, built. It shall no longer be a burden on your shoulders. Now serve the Lord your God and His people Israel.

4Prepare yourselves according to your fathers’ houses, according to your divisions, following the written instruction of David king of Israel and the written instruction of Solomon his son.
