Leviticus 7:21

18 and if any of the flesh of the sacrifice of his peace-offerings be really eaten on the third day, it is not pleasing; for him who is bringing it near it is not reckoned; it is an abominable thing, and the person who is eating of it his iniquity doth bear.

19 `And the flesh which cometh against any unclean thing is not eaten; with fire it is burnt; as to the flesh, every clean one doth eat of the flesh;

20 and the person who eateth of the flesh of the sacrifice of the peace-offerings which [are] Jehovah`s, and his uncleanness upon him, even that person hath been cut off from his people.

21 `And when a person cometh against any thing unclean, of the uncleanness of man, or of the uncleanness of beasts, or of any unclean teeming creature, and hath eaten of the flesh of the sacrifice of the peace-offerings which [are] Jehovah`s, even that person hath been cut off from his people.`

22 And Jehovah speaketh unto Moses, saying,

23 `Speak unto the sons of Israel, saying, Any fat of ox and sheep and goat ye do not eat;

24 and the fat of a carcase, and the fat of a torn thing is prepared for any work, but ye do certainly not eat it;
