Leviticus 7:16-18

16But if the sacrifice of his offering is a 1votive or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the 2next day what is left of it may be eaten; 173but what is left over from the flesh of the sacrifice on the third day shall be burned with fire. 18So if any of the flesh of the sacrifice of his peace offerings should ever be eaten on the third day, he who offers it will not be accepted, and it will not be reckoned to his benefit. It shall be an 4offensive thing, and the person who eats of it will bear his own iniquity.
