Leviticus 7:15-17

ISV^{(i) 15} As to the meat contained in his peace offerings, it is to be eaten on the day it is offered. Nothing of it is to remain until morning.”
¹⁶ Voluntary Offerings“If his sacrifice accompanies a fulfilled vow or is a voluntary offering, it is to be eaten on the day the offeror brings the sacrifice. Anything left over is to be eaten the next day, ¹⁷ but whatever remains uneaten from the meat of the sacrifice by the third day is to be incinerated.
