Leviticus 7:21-25

²¹Moreover, the soul that shall touch any unclean thing , as the uncleanness of man, or any unclean beast, or any abominable unclean thing , and eat of the flesh of the sacrifice of peace-offerings which pertain to the LORD, even that soul shall be cut off from his people.

²²And the LORD spoke to Moses, saying,

²³Speak to the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat.

²⁴And the fat of the beast that dieth of itself, and the fat of that which is torn with beasts, may be used for any other purpose; but ye shall in no wise eat of it.

²⁵For whoever eateth the fat of the beast, of which men offer an offering made by fire to the LORD, even the soul that eateth it shall be cut off from his people.
