Leviticus 20:14-16 New American Standard Bible (NASB)

14. If there is a man who marries a woman and her mother, it is immorality; both he and they shall be burned with fire, so that there will be no immorality in your midst.

15. If there is a man who lies with an animal, he shall surely be put to death; you shall also kill the animal.

16. If there is a woman who approaches any animal to mate with it, you shall kill the woman and the animal; they shall surely be put to death. Their bloodguiltiness is upon them.
