1 Corinthians 7:38-40 English Standard Version (ESV)

38. So then he who marries his betrothed does well, and he who refrains from marriage will do even better.

39. A wife is bound to her husband as long as he lives. But if her husband dies, she is free to be married to whom she wishes, only in the Lord.

40. Yet in my judgment she is happier if she remains as she is. And I think that I too have the Spirit of God.
