Leviticus 19:6

New Revised Standard Version Catholic Interconfessional

It shall be eaten on the same day you offer it, or on the next day; and anything left over until the third day shall be consumed in fire.

See the chapter Copy

You shall let none of it remain until the morning; anything that remains until the morning you shall burn.

When you offer a sacrifice of well-being to the Lord, offer it in such a way that it is acceptable on your behalf.

If it is eaten at all on the third day, it is an abomination; it will not be acceptable.
