1 Corinthians 7:36-40

But if any man thinks that he is not acting properly and honorably toward his virgin daughter, [by not permitting her to marry], if she is past her youth, and it must be so, let him do as he wishes, he does not sin; let her marry. But the man who stands firmly committed in his heart, having no compulsion [to yield to his daughter’s request], and has authority over his own will, and has decided in his own heart to keep his own virgin [daughter from being married], he will do well. So then both the father who gives his virgin daughter in marriage does well, and he who does not give her in marriage will do better. A wife is bound [to her husband by law] as long as he lives. But if her husband dies, she is free to marry whomever she wishes, only [provided that he too is] in the Lord. But in my opinion a widow is happier if she stays as she is. And I think that I also have the Spirit of God [in this matter].
