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 other priests had sanctified themselves: for the Levites were more upright in heart to sanctify themselves than the priests.1

35And also the burnt offerings were in abundance, with the fat of the peace offerings, and the drink offerings for every burnt offering. So the service of the house of the Lord was set in order.

36And Hezekiah rejoiced, and all the people, that God had prepared the people: for the thing was done suddenly.
