Leviticus 7:15-17

New Century Version

¹⁵ When the fellowship offering is given to thank the Lord, the meat from it must be eaten the same day it is offered; none of it must be left until morning.

¹⁶ “‘If a person brings a fellowship offering just to give a gift to God or because of a special promise to him, the sacrifice should be eaten the same day he offers it. If there is any left, it may be eaten the next day. ¹⁷ If any meat from this sacrifice is left on the third day, it must be burned up.
