Leviticus 18:23-25

²³And thou shalt not lie with any beast to defile thyself therewith; neither shall any woman stand before a beast, to lie down thereto; it is perversion.

²⁴Defile not ye yourselves in any of these things; for in all these the nations are defiled, which I cast out from before you.

²⁵And the land was defiled, therefore I did visit the iniquity thereof upon it, and the land vomited out her inhabitants.
