1 Corinthians 7:8-11

7:8 To the unmarried and widows I say that it is best for them to remain as I am. 7:9 But if they do not have self-control, let them get married. For it is better to marry than to burn with sexual desire.

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.
