Leviticus 7:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ But if the sacrifice you offer is a votive offering or a freewill-offering, it shall be eaten on the day that you offer your sacrifice, and what is left of it shall be eaten the next day; ¹⁷ but what is left of the flesh of the sacrifice shall be burned on the third day. ¹⁸ If any of the flesh of your sacrifice of well-being is eaten on the third day, it shall not be acceptable, nor shall it be credited to the one who offers it; it shall be an abomination, and the one who eats of it shall incur guilt.
