Leviticus 18:26-28

Ye shall therefore keep my statutes and my judgments, and shall not commit {any} of these abominations; {neither} any of your own nation, nor any stranger that sojourneth among you: (For all these abominations have the men of the land done, which {were} before you, and the land is defiled;) That the land spue not you out also, when ye defile it, as it spued out the nations that {were} before you.
