Leviticus 7:18; Leviticus 19:7

18 'So if any of the flesh of the sacrifice of his peace offerings should ever be eaten on the third day, he who offers it will not be accepted, and it will not be reckoned to his benefit. It shall be an offensive thing, and the person who eats of it will bear his own iniquity.

7 'So if it is eaten at all on the third day, it is an offense; it will not be accepted.
