2 Chronicles 29:34-36

34But there were too few priests and they were unable to skin all the burnt offerings; so until the other priests had consecrated themselves, their brothers, the Levites, helped them until the work was done. For the Levites were more upright in heart and more conscientious than the priests in consecrating themselves.

35There were also many burnt offerings with the fat of the peace offerings and with the drink offerings for the burnt offerings. So the service of the house of the Lord was established again.

36Then Hezekiah and all the people rejoiced because of what God had prepared for the people, for the thing came about suddenly.
