Leviticus 7:17-18; Leviticus 19:6-7
but what is left over from the flesh of the sacrifice on the third day shall be burned with fire.
'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.
'It shall be eaten the same day you offer it, and the next day; but what remains until the third day shall be burned with fire.
'So if it is eaten at all on the third day, it is an offense; it will not be accepted.
