Leviticus 20:9

20:9 For every one that curseth his father or his mother shall be surely put to death: he hath cursed his father or his mother; his blood [shall be] upon him.

Leviticus 20:11-12

20:11 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. 20:12 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.
