Leviticus 18:26-30

You shall therefore keep My statutes and My judgments, and shall not commit any of these abominations, either any of your own nation or any stranger who dwells among you (for all these abominations the men of the land have done, who were before you, and thus the land is defiled), lest the land vomit you out also when you defile it, as it vomited out the nations that were before you. For whoever commits any of these abominations, the persons who commit them shall be cut off from among their people. ‘Therefore you shall keep My ordinance, so that you do not commit any of these abominable customs which were committed before you, and that you do not defile yourselves by them: I am the LORD your God.’ ”
