Leviticus 7:18-20

Amplified Bible

¹⁸ If any of the meat of the sacrifice of his peace offerings is ever eaten on the third day, then it will not be accepted, and the one who brought it will not be credited with it. It shall be an abhorred (offensive) thing; the one who eats it shall bear his own guilt.

¹⁹ ‘The meat that comes in contact with anything that is unclean shall not be eaten; it shall be burned in the fire. As for other meat, everyone who is [ceremonially] clean may eat it. ²⁰ But the one who eats meat from the sacrifice of peace offerings which belong to the Lord, in his uncleanness, that person shall be ^[a]cut off from his people [excluding him from the atonement made for them].
