Romanos 7

2 For the married woman is bound by law to her husband so long as he is alive; but if the husband should die, she is clear from the law of the husband:

3 so then, the husband being alive, she shall be called an adulteress if she be to another man; but if the husband should die, she is free from the law, so as not to be an adulteress, though she be to another man.
