1 Corinthians 7:38-42

So then, both the one who gives his own virgin in marriage does well, and the one who does not give her in marriage will do better.

A wife is bound as long as her husband lives; but if her husband dies, she is free to be married to whom she wishes, only in the Lord.

But in my opinion she is happier if she remains as she is; and I think that I also have the Spirit of God.
