Leviticus 19:5-7

New Century Version

⁵ “‘When you sacrifice a fellowship offering to the Lord, offer it in such a way that will be accepted. ⁶ You may eat it the same day you offer it or on the next day. But if any is left on the third day, you must burn it up. ⁷ If any of it is eaten on the third day, it is unclean, and it will not be accepted.
