1 Corinthians 7:39-40 Amplified Bible (AMP)

39. A wife is bound to her husband by law as long as he lives. If the husband dies, she is free to be married to whom she will, only [provided that he too is] in the Lord.

40. But in my opinion [a widow] is happier (more blessed and to be envied) if she does not remarry. And also I think I have the Spirit of God.
