Leviticus 7:18-21

18If any of the meat of the sacrifice of his fellowship offerings is eaten on the third day, it will not be accepted, nor will it be credited to him who offers it. It will be a foul thing—and the soul who eats any from it will bear his own iniquity.

19“The meat that touches any unclean thing is not to be eaten. It is to be burned up with fire. As for the meat, everyone who is clean may eat it,

20but the soul who eats of the meat of the sacrifice of fellowship offerings belonging to Adonai, having his uncleanness on him, that soul is to be cut off from his people.

21If anyone touches any unclean thing, whether the uncleanness of man, or an unclean animal or any unclean detestable thing, and eats some of the meat of the sacrifice of fellowship offerings belonging to Adonai, that soul is to be cut off from his people.”
