Leviticus 7:15-21

15And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning. 16But if the sacrifice of his offering shall be a vow, or a voluntary offering, it shall be eaten the same day that he offereth his sacrifice: and on the next day also the remainder of it shall be eaten: 17But the remainder of the flesh of the sacrifice on the third day shall be burnt with fire. 18And if any of the flesh of the sacrifice of his peace offerings shall be eaten at all on the third day, it shall not be accepted, neither shall it be imputed to 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 shall be clean shall eat of it. 20But the soul that eateth of the flesh of the sacrifice of peace offerings, that pertain to the LORD, having his uncleanness upon him, even that soul shall be cut off from his people. 21Moreover 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 to the LORD, even that soul shall be cut off from his people.
