Leviticus 18:24-28

24“ ‘Do not defile yourselves in any of these ways, because this is how the nations that I am going to drive out before you became defiled.

25Even the land was defiled; so I punished it for its sin, and the land vomited out its inhabitants.

26But you must keep my decrees and my laws. The native-born and the foreigners residing among you must not do any of these detestable things,

27for all these things were done by the people who lived in the land before you, and the land became defiled.

28And if you defile the land, it will vomit you out as it vomited out the nations that were before you.
