Leviticus 18:25-30

The land has become unclean, and I punished it for its sins, so the land is throwing out those people who live there. “ ‘You must obey my laws and rules, and you must not do any of these hateful sins. These rules are for the citizens of Israel and for the people who live with you. The people who lived in the land before you did all these hateful things and made the land unclean. If you do these things, you will also make the land unclean, and it will throw you out as it threw out the nations before you. Anyone who does these hateful sins must be cut off from the people. Keep my command not to do these hateful sins that were done by the people who lived in the land before you. Don’t make yourself unclean by doing them. I am the LORD your God.’ ”
