Romans 7:1-3

Or do you not know, brothers and sisters (for I am speaking to those who know the Law), that the Law has jurisdiction [to rule] over a person as long as he lives? For the married woman [as an example] is bound and remains bound by law to her husband while he lives; but if her husband dies, she is released and exempt from the law concerning her husband. Accordingly, she will be designated as an adulteress if she unites herself to another man while her husband is alive. But if her husband dies, she is free from the law [regarding marriage], so that she is not an adulteress if she marries another man.
