1 Corinthians 7:35-39

I say this for your own benefit, not to put a restraint on you, but to promote what is appropriate and to secure undistracted devotion to the Lord.

But if anyone thinks that he is acting dishonorably toward his virgin, if she is past her youth and it ought to be so, let him do what he wishes, he is not sinning; let them marry.

But the one who stands firm in his heart, if he is not under constraint, but has authority over his own will, and has decided this in his own heart, to keep his own virgin, he will do well.

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.
