Leviticus 7:15-17

American Standard Version

¹⁵ And the flesh of the sacrifice of his peace-offerings for thanksgiving shall be eaten on the day of his oblation; he shall not leave any of it until the morning. ¹⁶ But if the sacrifice of his oblation be a vow, or a freewill-offering, it shall be eaten on the day that he offereth his sacrifice; and on the morrow that which remaineth of it shall be eaten: ¹⁷ but that which remaineth of the flesh of the sacrifice on the third day shall be burnt with fire.
