But I say to you that whoever divorces his wife, except for sexual unfaithfulness, causes her to commit adultery. And whoever marries her who is divorced commits adultery.
So then, she will be called an adulteress if she marries another man while her husband lives. But if her husband dies, she is free from that law, so that she would not be an adulteress if she marries another man.
The wife does not have authority over her own body, but the husband does. Likewise, the husband does not have authority over his own body, but the wife does.
