1 Corinthians 7:38 – 40
New International Version (NIV)
38 So then, he who marries the virgin does right, but he who does not marry her does better.
39 A woman is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, but he must belong to the Lord. 40 In my judgment, she is happier if she stays as she is — and I think that I too have the Spirit of God.
