Leviticus 7:16-18

16“If the sacrifice he offers is a vow or a freewill offering, it is to be eaten on the day he presents his sacrifice, and what is left over may be eaten on the next day.

17But what remains of the sacrificial meat by the third day must be burned.

18If any of the meat of his fellowship sacrifice is eaten on the third day, it will not be accepted. It will not be credited to the one who presents it; it is repulsive. The person who eats any of it will bear his iniquity.
