Leviticus 18:27-29 New King James Version (NKJV)

27. (for all these abominations the men of the land have done, who were before you, and thus the land is defiled),

28. lest the land vomit you out also when you defile it, as it vomited out the nations that were before you.

29. For whoever commits any of these abominations, the persons who commit them shall be cut off from among their people.
