Leviticus 7:15-17

Amplified Bible

¹⁵ ‘The meat of the sacrifice of thanksgiving presented as a peace offering shall be eaten on the day that it is offered; none of it shall be left until morning. ¹⁶ But if the sacrifice of his offering is a vow or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the next day that which remains of it may be eaten; ¹⁷ but what is left over from the meat of the sacrifice on the third day shall be [completely] burned in the fire.
