Leviticus 7:15-18

15And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten on the day of his offering. He shall not leave any of it until the morning. 16But if the sacrifice of his offering is a vow offering or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the next day what remains of it shall be eaten. 17But what remains of the flesh of the sacrifice on the third day shall be burned up with fire. 18If any of the flesh of the sacrifice of his peace offering is eaten on the third day, he who offers it shall not be accepted, neither shall it be credited to him. It is tainted, and he who eats of it shall bear his iniquity.
