Leviticus [Pertaining to Levites] 7:17-18

¹⁷but what remains of the meat of the sacrifice on the third day shall be burned with fire.

¹⁸If any of the meat of the sacrifice of his peace offerings is eaten on the third day, it will not be accepted, and it shall not be credited to him who offers it. It will be an abomination, and the soul who eats any of it will bear his iniquity.
