11
And the man that lieth with his father’s wife hath uncovered his father’s nakedness: both of them shall surely be put to death; their blood shall be upon them.
12
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.
