TSK · Leviticus 3:15

Then he must remove all of its fat(just as fat was removed from the peace offering sacrifice) and the priest must offer it up in smoke on the altar for a soothing aroma to the LORD. So the priest will make atonement on his behalf and he will be forgiven.

There was a large number of burnt sacrifices, as well as fat from the peace offerings and drink offerings that accompanied the burnt sacrifices. So the service of the LORD’s temple was reinstituted.
