Leviticus 7:18-20

¹⁸And if any of the flesh of the sacrifice of his peace-offerings be eaten on the third day, it shall not be accepted, neither shall it be imputed unto him that offereth it: it shall be an abomination, and the soul that eateth of it shall bear his iniquity.

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