Leviticus 7:15-18

15‘1Now as for the flesh of the sacrifice of his thanksgiving peace offerings, it shall be eaten on the day of his offering; he shall not leave any of it over until morning. 16But if the sacrifice of his offering is a 23vow or a 4voluntary offering, it shall be eaten on the day that he offers his sacrifice, and on the next 5day what is left of it may be eaten; 176but 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 is ever eaten on the third day, he who offers it will not be accepted, and it will not be credited to him. It will be an 7unclean thing, and the person who eats it shall bear his punishment.
