Leviticus 7:24-26

Amplified Bible

²⁴ The fat of an animal which dies [of natural causes] and the fat of one which is torn [to pieces by a predator] may be put to any other use, but under no circumstances are you to eat it. ²⁵ For whoever eats the fat of the animal from which an offering by fire is presented to the Lord, that person who eats shall be cut off from his people [excluding him from the atonement made for them]. ²⁶ Moreover, you are not to eat any blood [of any kind], whether of bird or animal, in any of your dwelling places.
