Also Jehoiada appointed the offices of the house of the LORD by the hand of the priests the Levites, whom David had distributed in the house of the LORD, to offer the burnt offerings of the LORD, as it is written in the law of Moses, with rejoicing and with singing, as it was ordained by David.
Jehoiada, along with the priests called Levites, set up the roles needed for running the Lord's house according to Moses' laws. They followed David's plan for these roles, performing special offerings happily and singing, just like David had instructed.
