Leviticus 18:24-28

Warning against the Abominations of the Nations

18:24 “‘Do not defile yourselves with any of these things, for the nations which I am about to drive out before you have been defiled with all these things. 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. 18:28 So do not make the land vomit you out because you defile it just as it has vomited out the nations that were before you.

Joshua 22:17-18

22:17 The sin we committed at Peor was bad enough. To this very day we have not purified ourselves; it even brought a plague on the community of the Lord. 22:18 Now today you dare to turn back from following the Lord! You are rebelling today against the Lord; tomorrow he may break out in anger against the entire community of Israel.
