Leviticus 7:18-20

¹⁸And if any of the flesh of the sacrifice of his peace offerings be eaten at all 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, all that be clean shall eat thereof. ²⁰But 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.
