Leviticus 19:5-8

5“‘When you sacrifice a peace offering sacrifice to the Lord, you must sacrifice it so that it is accepted for you.

6It must be eaten on the day of your sacrifice and on the following day, but what is left over until the third day must be burned up.

7If, however, it is eaten on the third day, it is spoiled, it will not be accepted,

8and the one who eats it will bear his punishment for iniquity because he has profaned what is holy to the Lord. That person will be cut off from his people.
