35 Also 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 Yahweh was set in order.

And also the burnt offerings were in abundance, with the fat of the peace offerings, and the drink offerings, for every burnt offering,.... Besides the abundance of burnt offerings, whose skins were to be taken off, there were meat offerings and drink offerings to each, which required many hands to prepare them; and also the fat of the peace offerings was to be burnt; which, all together, occasioned a great deal of business:
so the service of the house of the Lord was set in order: both for sacrifice and singing; a good beginning was made, and there was a good foundation laid to proceed on.
2-Chronicles 29:35 gives yet another reason why the Levites had to help the priests: "And also the burnt-offerings were in abundance, with the fat of the peace-offerings, and the drink-offerings for every burnt-offering." The priests could not accomplish the flaying for this reason also, that they had, besides, to see to the proper altar service (sprinkling of the blood, and burning of the sacrifices upon the altar), which taxed their strength, since, besides the consecratory burnt-offerings, there were the voluntary burnt-offerings (2-Chronicles 29:31), which were offered along with the thank-offerings and the drink-offerings, which belonged to the burnt-offerings of Numbers 15:1-15. Thus the service of the house of Jahve was arranged. עבודה is not the purification and dedication of the temple (Berth.), but only the sacrificial service, or rather all that concerned the regular temple worship, which had decayed under Ahaz, and had at length wholly ceased.
