Leviticus 7:18-20

New Revised Standard Version, Anglicised Catholic Edition

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.

¹⁹ Flesh that touches any unclean thing shall not be eaten; it shall be burned. As for other flesh, all who are clean may eat such flesh. ²⁰ But those who eat flesh from the Lord’s sacrifice of well-being while in a state of uncleanness shall be cut off from their kin.
