Leviticus 18:25-27

18:25 Therefore the land has become unclean and I have brought the punishment for its iniquity upon it, so that the land has vomited out its inhabitants. 18:26 You yourselves must obey my statutes and my regulations and must not do any of these abominations, both the native citizen and the resident foreigner in your midst, 18:27 for the people who were in the land before you have done all these abominations, and the land has become unclean.
