1 Corinthians 7:10-11

7:10 To the married I give this command – not I, but the Lord – a wife should not divorce a husband 7:11 (but if she does, let her remain unmarried, or be reconciled to her husband), and a husband should not divorce his wife.

1 Corinthians 7:39-40

7:39 A wife is bound as long as her husband is living. But if her husband dies, she is free to marry anyone she wishes (only someone in the Lord). 7:40 But in my opinion, she will be happier if she remains as she is – and I think that I too have the Spirit of God!
