Leviticus 7:17-18

¹⁷But any meat that is left until the third day must be completely burned.

¹⁸If any meat from the offering to maintain fellowship with Yahweh is eaten on the third day, Yahweh will not accept that offering; it will be useless to offer it, because Yahweh will consider that it is worthless. Anyone who eats some of it will have to pay a penalty to Yahweh.
