2 Chronicles 29:32

30 Moreover, King Hezekiah and the officials ordered the Levites to sing praises to the LORD with the words of David and Asaph the seer. So they sang praises with joy, and bowed down and worshiped.

31 Then Hezekiah said, "Now that you have consecrated yourselves to the LORD , come near and bring sacrifices and thank offerings to the house of the LORD ." And the assembly brought sacrifices and thank offerings, and all those who were willing brought burnt offerings.

32 The number of the burnt offerings which the assembly brought was 70 bulls, 100 rams, and 200 lambs; all these were for a burnt offering to the LORD .

33 The consecrated things were 600 bulls and 3,000 sheep.

34 But the priests were too few, so that they were unable to skin all the burnt offerings; therefore their brothers the Levites helped them until the work was completed and until the other priests had consecrated themselves. For the Levites were more conscientious to consecrate themselves than the priests.
