1 Corinthians 7:38-40

38 So then he that gives her in marriage does well; but he that gives her not in marriage does better.

39 The wife is bound by the law as long as her husband lives; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord.

40 But she is happier if she so abide, after my judgment: and I think also that I have the Spirit of God.
