Leviticus 20:14-16

New Revised Standard Version Catholic Edition

¹⁴ If a man takes a wife and her mother also, it is depravity; they shall be burned to death, both he and they, that there may be no depravity among you. ¹⁵ If a man has sexual relations with an animal, he shall be put to death; and you shall kill the animal. ¹⁶ If a woman approaches any animal and has sexual relations with it, you shall kill the woman and the animal; they shall be put to death, their blood is upon them.
