Leviticus 18:23-25

New Revised Standard Version Catholic Edition

²³ You shall not have sexual relations with any animal and defile yourself with it, nor shall any woman give herself to an animal to have sexual relations with it: it is perversion.

²⁴ Do not defile yourselves in any of these ways, for by all these practices the nations I am casting out before you have defiled themselves. ²⁵ Thus the land became defiled; and I punished it for its iniquity, and the land vomited out its inhabitants.
