Leviticus 3:1, 7-17

“If his offering is a fellowship sacrifice,  and he is presenting an animal from the herd, whether male or female, he is to present one without blemish  before the Lord.

If he is presenting a lamb for his offering, he is to present it before the Lord. He must lay his hand on the head of his offering, then slaughter it before the tent of meeting. Aaron’s sons will splatter its blood on all sides of the altar. He will then present part of the fellowship sacrifice as a food offering to the Lord consisting of its fat and the entire fat tail,  which he is to remove close to the backbone. He will also remove the fat surrounding the entrails,  all the fat on the entrails, the two kidneys with the fat on them at the loins, and the fatty lobe of the liver above the kidneys. Then the priest will burn the food on the altar,  as a food offering to the Lord. “If his offering is a goat,  he is to present it before the Lord. He must lay his hand on its head and slaughter it before the tent of meeting. Aaron’s sons will splatter  its blood on all sides of the altar. He will present part of his offering as a food offering to the Lord: the fat surrounding the entrails, all the fat that is on the entrails, and the two kidneys with the fat on them at the loins; he will also remove the fatty lobe of the liver with the kidneys. Then the priest will burn the food on the altar, as a food offering for a pleasing aroma.  “All fat belongs to the Lord. This is a permanent statute  throughout your generations, wherever you live: you must not eat any fat or any blood.”
