Leviticus 7:22

But the soul that eateth [of] the flesh of the sacrifice of peace offerings, that [pertain] unto the LORD, having his uncleanness upon him, even that soul shall be cut off from his people.

Moreover 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] unto the LORD, even that soul shall be cut off from his people.

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

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