Leviticus 7:17 TLB

[17] But anything left over until the third day shall be burned. For if any of it is eaten on the third day, the Lord will not accept it; it will have no value as a sacrifice, and there will be no credit to the one who brought it to be offered; and the priest who eats it shall be guilty, for it is detestable to the Lord, and the person who eats it must answer for his sin.
