2 Chronicles 29:34-36

34But the priests were too few, so that they could not flay all the burnt-offerings: wherefore their brethren the Levites did help them, till the work was ended, and until the priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests. 35And also the burnt-offerings were in abundance, with the fat of the peace-offerings, and with the drink-offerings for every burnt-offering. So the service of the house of Jehovah was set in order. 36And Hezekiah rejoiced, and all the people, because of that which God had prepared for the people: for the thing was done suddenly.
