Leviticus 7:16-18

New Catholic Bible

¹⁶ But if the offering is a vow offering or a freewill offering, it is be eaten on the day that it was offered, and the leftovers must be eaten the next day. ¹⁷ Whatever is still left over until the third day must be burned in the fire. ¹⁸ If someone eats the meat of a peace offering on the third day, the offering shall not be pleasing. It shall be of no benefit to the person who offered it. It shall be an abomination, and whoever eats of it shall bear the guilt of his iniquity.
