1 Corinthians 7:9-11

New International Version - UK

⁹ But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.

¹⁰ To the married I give this command (not I, but the Lord): a wife must not separate from her husband. ¹¹ But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
