Leviticus 7:18-21

18If the person eats the meat on the third day, God will not accept the gift. The meat is not good. The person who eats it will not give God pleasure.

19Some meat may touch something that is not clean. Nobody should eat that meat. People must burn it. Only a clean person can eat the meat that is a gift to God.

20A person who is not clean might eat the friendship offering to the Lord. If he does, they must send him away from Israel's people.

21A person might touch something that is not clean. He must not eat the meat of the offering to the Lord. That person must not eat it if he has touched an unclean animal or an unclean person. If he does eat it, they must send him away. They must send him away from Israel's people.’
