2 Chronicles 35:3-4

3The work of the Levites was to teach all the Israelites about God's laws. The Lord had chosen them to do that special work. Josiah said to them, ‘Put the holy Covenant Box in the temple that David's son, King Solomon, built. Do not carry it on your shoulders. Now you must serve the Lord your God and his people, the Israelites.

4Each group of families must be ready to do their work. King David of Israel and his son Solomon decided what work each group must do.
