Leviticus 20:10-12

10“The man who commits adultery with another man’s wife, who commits adultery with his friend’s wife, both the adulterer and the adulteress should surely be put to death.

11“If a man lies with his father’s wife, and has uncovered his father’s nakedness, both of them should surely be put to death, and their blood should be on them.

12If a man lies with his daughter-in-law, both of them should surely be put to death. They have committed a perversion, and their blood should be on them.
