2 Chronicles 29:34-36

34However, since there were not enough priests to skin all the burnt offerings, their Levite brothers helped them until the work was finished and until the priests had consecrated themselves. For the Levites had been more diligent in consecrating themselves than the priests had been.

35Furthermore, the burnt offerings were abundant, along with the fat of the peace offerings and the drink offerings for the burnt offerings. So the service of the house of the LORD was established. 36Then Hezekiah and all the people rejoiced at what God had prepared for the people, because everything had been accomplished so quickly.
