1 Corinthians 7:36-40

But if any man thinks that he is acting unbecomingly toward his virgin daughter, if she is past her youth, and if it must be so, let him do what he wishes, he does not sin; let her marry. But he who stands firm in his heart, being under no constraint, but has authority over his own will, and has decided this in his own heart, to keep his own virgin daughter, he will do well. So then both he who gives his own virgin daughter in marriage does well, and he who does not give her in marriage will do better. A wife is bound as long as her husband lives; but if her husband is dead, 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.
