Leviticus 7:18-20

New Century Version

¹⁸ Any meat of the fellowship offering eaten on the third day will not be accepted, nor will the sacrifice count for the person who offered it. It will become unclean, and anyone who eats the meat will be guilty of sin.

¹⁹ “‘People must not eat meat that touches anything unclean; they must burn this meat with fire. Anyone who is clean may eat other meat. ²⁰ But if anyone is unclean and eats the meat from the fellowship offering that belongs to the Lord, he must be cut off from his people.
