Leviticus 20:12

If a man lies with his daughter-in-law , both of them shall surely be put to death ; they have committed perversion ; their blood is upon them.

“‘If a man has sexual relations with his daughter-in-law, both of them are to be put to death. What they have done is a perversion; their blood will be on their own heads.

And if a man lie with his daughter in law, both of them shall surely be put to death : they have wrought confusion; their blood shall be upon them.
