Romans 7:1-3

Certainly you will understand what I am about to say, my friends, because all of you know about law. The law rules over people only as long as they live. A married woman, for example, is bound by the law to her husband as long as he lives; but if he dies, then she is free from the law that bound her to him. So then, if she lives with another man while her husband is alive, she will be called an adulteress; but if her husband dies, she is legally a free woman and does not commit adultery if she marries another man.
