Leviticus 7:19-25

19And the flesh that toucheth any unclean thing shall not be eaten; it shall be burnt with fire: and as for the flesh, all that be clean shall eat thereof. 20But the soul that eateth of the flesh of the sacrifice of peace offerings, that pertain unto Yhwh, having his uncleanness upon him, even that soul shall be cut off from his people. 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 unto Yhwh, even that soul shall be cut off from his people.

22And Yhwh spake unto Moses, saying, 23Speak unto 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 in any other use: but ye shall in no wise eat of it.1 25For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto Yhwh, even the soul that eateth it shall be cut off from his people.
