Leviticus 7:12-16

¹²If you offer it in a spirit of thanks, then along with the sacrifice of thanksgiving, you must offer bread, wafers, and well-kneaded cakes of the best flour all made without yeast and mixed or coated with olive oil.

¹³In addition your peace offering of thanksgiving of breads made without yeast, you shall present an offering of breads made with yeast.

¹⁴Present one of each kind of bread of the offering as a contribution to the Lord. It is for the priest who sprinkles the blood of the peace offering.

¹⁵The meat of the sacrifice of your peace offering of thanksgiving must be eaten the same day you offer it. Don't leave any of it until the morning.

¹⁶If the sacrifice you're offering is to pay a vow or a freewill offering, it shall be eaten on the day you present your sacrifice, but what's left can be eaten the next day.
