Leviticus 18:24-30

Do not defile yourselves in any of these ways, for in all these things the nations are defiled which I am casting out before you. And the land is defiled; therefore I visit the iniquity of it upon it, and the land itself vomits out her inhabitants. So you shall keep My statutes and My ordinances and shall not commit any of these abominations, neither the native-born nor any stranger who sojourns among you, For all these abominations have the men of the land done who were before you, and the land is defiled– [Do none of these things] lest the land spew you out when you defile it as it spewed out the nation that was before you. Whoever commits any of these abominations shall be cut off from among [his] people. So keep My charge: do not practice any of these abominable customs which were practiced before you and defile yourselves by them. I am the Lord your God.
