Romanos 7

2 For the woman who is under a man has been bound by law to the living husband. But if the husband should die, she is released from the law of the husband.

3 So then, while the husband is living, she will be called an adulteress if she becomes [married] to a different husband; but if her husband should die, she is free from the law, so that she is not an adulteress, having become [married] to a different husband.
