A wife is bound by the law to her husband for as long as he lives. But if her husband dies, she is free to be married to anyone she wishes, but only in the Lord.
Now to the married I give this command (not I, but the Lord): A wife must not separate from her husband
But if the unbelieving spouse separates, let it be so. The brother or the sister is not enslaved in such cases. God has called us to live in peace.
So then, he who gives her in marriage does well, but he who does not give her in marriage does better.
