Leviticus 19:5-8 New King James Version (NKJV)
5 ‘And if you offer a sacrifice of a peace offering to the Lord, you shall offer it of your own free will. 6 It shall be eaten the same day you offer it, and on the next day. And if any remains until the third day, it shall be burned in the fire. 7 And if it is eaten at all on the third day, it is an abomination. It shall not be accepted. 8 Therefore everyone who eats it shall bear his iniquity, because he has profaned the hallowed offering of the Lord; and that person shall be cut off from his people.
