Leviticus 20:16-18

New Revised Standard Version Catholic Edition

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.

¹⁷ If a man takes his sister, a daughter of his father or a daughter of his mother, and sees her nakedness, and she sees his nakedness, it is a disgrace, and they shall be cut off in the sight of their people; he has uncovered his sister’s nakedness, he shall be subject to punishment. ¹⁸ If a man lies with a woman having her sickness and uncovers her nakedness, he has laid bare her flow and she has laid bare her flow of blood; both of them shall be cut off from their people.
