Leviticus 19:6-8

6 It shall be eaten the same day you offer it or on the day after, and anything left over until the third day shall be burned up with fire. 7 If it is eaten at all on the third day, it is a tainted; it will not be accepted, 8 and everyone who eats it shall b bear his iniquity, because c he has profaned what is holy to the  Lord, and that person shall be cut off from his people.
