Leviticus 7:20-21

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.
