For the woman who has a husband is bound by the law to her husband so long as he lives; but if the husband dies, she is loosed from the law of her husband.
All Commentaries on Romans 7:2 Go To Romans 7
Tertullian of Carthage
AD 220
If, however, the husband shall have died, she has been freed from (his) law, (so) that she is not an adulteress if made (wife) to another husband."
