2 Chronicles 29:34-36

34The kohanim, however, were too few to flay all the burnt offerings, so their kinsmen, the Levites, helped them until the work was completed, and until other kohanim had consecrated themselves. For the Levites had been more conscientious to consecrate themselves than the kohanim.

35There were also a great many burnt offerings, along with the fat of the peace offerings and the drink offering at every burnt offering. Thus the avodah of the House of Adonai was reestablished.

36Hezekiah and all the people rejoiced because of what God had enabled the people to accomplish, because it happened so suddenly.
