1 Corinthians 7:40

³⁸  So then he that giveth her in marriage doeth well; but he that giveth her not in marriage doeth better.

³⁹  The wife is bound by the law as long as her husband liveth; 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.
