TSK · Leviticus 3:15

And he shall take away all the fat thereof, as the fat is taken away from off the sacrifice of peace offerings; and the priest shall burn [it] upon the altar for a sweet savour unto the LORD; and the priest shall make an atonement for him, and it shall be forgiven him.

And also the burnt offerings [were] in abundance, with the fat of the peace offerings, and the drink offerings for [every] burnt offering. So the service of the house of the LORD was set in order.
