7:17 but the leftovers from the meat of the sacrifice must be burned up in the fire on the third day.
7:18 If some of the meat of his peace offering sacrifice is ever eaten on the third day it will not be accepted; it will not be accounted to the one who presented it, since it is spoiled, and the person who eats from it will bear his punishment for iniquity.
