Romanos 7

2 For a married woman who has a husband is bound by law to her husband during his lifetime; but if her husband dies, she is released from the law of her husband.

3 So then, if during her husband lifetime, she unites herself with another man, she will be counted an adulteress; but if her husband dies, she is free from the Law, so that she is no adulteress, even if she unites herself with another man.
