2 Chronicles 29:34-36

34But the priests were too few, so that they could not skin all the burnt offerings; therefore their brethren the Levites helped them until the work was ended and until the other priests had sanctified themselves, for the Levites were more diligent in sanctifying themselves than the priests.

35Also 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 the Lord was set in order.

36Then Hezekiah and all the people rejoiced that God had prepared the people, since the events took place so suddenly.
