2 Chronicles 29:31-35

31Then Hezekiah said, “Now that you have consecrated yourselves to the LORD,1 come near and bring sacrifices and thank offerings to the house of the LORD.”

So the assembly brought sacrifices and thank offerings, and all whose hearts were willing brought burnt offerings. 32The number of burnt offerings the assembly brought was seventy bulls, a hundred rams, and two hundred lambs; all these were for a burnt offering to the LORD. 33And the consecrated offerings were six hundred bulls and three thousand sheep.

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.
