(12) With his daughter in law.--See Notes on Leviticus 18:15.

20:10-27 These verses repeat what had been said before, but it was needful there should be line upon line. What praises we owe to God that he has taught the evil of sin, and the sure way of deliverance from it! May we have grace to adorn the doctrine of God our Saviour in all things; may we have no fellowship with unfruitful works of darkness, but reprove them.If a man lie with his daughter in law,.... His son's wife, whether in the lifetime of his son, or after his death, or whether she was espoused or married, according to the above tradition (f):

both of them shall surely be put to death; it being a breach of the law in Leviticus 18:15; and this is the penalty annexed to it, even death:

they have wrought confusion: have been guilty of a shocking and shameful mixture, as Jarchi and Ben Gersom, as well as confounded the degrees of relation and affinity:

their blood shall be upon them; it being a capital crime, their, blood shall be shed for it; they shall be found guilty of death by stoning, as the Targum of Jonathan.
