What does 2 Chronicles 35:4 mean?

He told the Levites, who taught all Israel and carried the holy chest, 'Put the sacred chest back in the temple Solomon, son of David, king of Israel, built. You don’t need to carry it around anymore. Now serve the Lord your God and his people Israel.' 2 Chronicles 35:4 - Modern Text Bible

(Josiah tells the Levites to settle the Ark in its place and focus on serving God and the people, not just moving things around.)
