Leviticus 20:14-16

New Catholic Bible

¹⁴ It is lewd for a man to marry a woman and her mother. Both he and they are to be burned with fire so that there might not be any lewdness among you. ¹⁵ If a man has sex with an animal, he must die. You shall also slay the animal. ¹⁶ If a woman approaches an animal to have sex with it, you shall kill both the woman and the animal. They must be put to death, for their blood is upon their own heads.
