Leviticus 7:15-16

15And the flesh of the sacrifice of his peace offerings afor thanksgiving shall be eaten on the day of his offering. He shall not leave any of it until the morning. 16But bif 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.
