Leviticus 3:6-11

“If your Peace-Offering to GOD comes from the flock, bring a male or female without defect. If you offer a lamb, offer it to GOD. Lay your hand on the head of your offering and slaughter it at the Tent of Meeting. The sons of Aaron will throw its blood on all sides of the Altar. As a Fire-Gift to GOD from the Peace-Offering, present its fat, the entire fat tail cut off close to the backbone, all the fat on and connected to the entrails, the two kidneys and the fat around them on the loins, and the lobe of the liver which is removed along with the kidneys. The priest will burn it on the Altar: a meal, a Fire-Gift to GOD.
