Leviticus 18:27-31

(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.

For whosoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people.

Therefore shall ye keep mine ordinance, that ye commit not any one of these abominable customs, which were committed before you, and that ye defile not yourselves therein: I am the LORD your God.
