Leviticus 19:5-8

5Now when you offer a sacrifice of peace offerings to the Lord, you shall offer it so that you may be accepted. 6It shall be eaten the same day you offer it, and the next day; but what remains until the third day shall be burned with fire. 7So if it is eaten at all on the third day, it is an offense; it will not be accepted. 8Everyone who eats it will bear his iniquity, for he has profaned the holy thing of the Lord; and that person shall be cut off from his people.
