And if any of the flesh of the sacrifice of his peace offerings be eaten at all on the third day, it shall not be accepted, neither shall it be imputed unto him that offereth it: it shall be an abomination, and the soul that eateth of it shall bear his iniquity.
If someone eats any part of their peace offering sacrifice on the third day, it won't be accepted and won't count for the person offering it. It will be considered very wrong, and the person who eats it will have to bear the guilt.
