Leviticus 7:19-21

19And the flesh that toucheth anything unclean shall not be eaten; it shall be burned with fire. And as to the flesh, all that are clean may eat [the] flesh.

20But the soul that eateth the flesh of the sacrifice of peace-offering which is for Jehovah, having his uncleanness upon him, that soul shall be cut off from his peoples.

21And if any one touch anything unclean, the uncleanness of man, or unclean beast, or any unclean abomination, and eat of the flesh of the sacrifice of peace-offering, which is for Jehovah, that soul shall be cut off from his peoples.
