Leviticus 18:23-25

Evangelical Heritage Version

²³ And you shall not give your emission to any animal, so that you become unclean by it. No woman shall stand in front of an animal to let it mate with her. It is an unnatural perversion.

²⁴ You must not make yourselves unclean in any of these ways, for in all these ways the nations that I am casting out before you have made themselves unclean. ²⁵ In this way the land became unclean, so I have come to deal with its guilt, and the land will vomit out its inhabitants.
