Leviticus 19:6

Legacy Standard Bible

It shall be eaten the same day you offer it and the next day; but what remains until the third day shall be burned with fire.

See the chapter Copy

‘Now when you offer a sacrifice of peace offerings to Yahweh, you shall offer it so that you may be accepted.

So if it is eaten at all on the third day, it is an offense; it will not be accepted.

And you shall not leave any of it over until morning, but whatever is left of it until morning, you shall burn with fire.
