Leviticus 20:10-12

10‘The man who commits adultery with another man’s wife, he who commits adultery with his neighbor’s wife, the adulterer and the adulteress, shall surely be put to death.

11The man who lies with his father’s wife has uncovered his father’s nakedness; both of them shall surely be put to death. Their blood shall be upon them.

12If a man lies with his daughter-in-law, both of them shall surely be put to death. They have committed perversion. Their blood shall be upon them.
