Leviticus 20:16-18

Revised Standard Version Catholic Edition

¹⁶ If a woman approaches any beast and lies with it, you shall kill the woman and the beast; 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 shameful thing, and they shall be cut off in the sight of the children of their people; he has uncovered his sister’s nakedness, he shall bear his iniquity. ¹⁸ If a man lies with a woman having her sickness, and uncovers her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood; both of them shall be cut off from among their people.
