Leviticus 7:18-20

¹⁸If any of the flesh of the sacrifice of his peace-offerings be eaten on the third day, it shall not be accepted, neither shall it be imputed to him who offers it: it shall be an abomination, and the soul who eats of it shall bear his iniquity.

¹⁹The flesh that touches any unclean thing shall not be eaten; it shall be burnt with fire. As for the flesh, everyone who is clean shall eat of it: ²⁰but the soul who eats of the flesh of the sacrifice of peace-offerings, that pertain to Yahweh, having his uncleanness on him, that soul shall be cut off from his people.
