1 Corinthians 7:6-11

Now as a concession, not a command, I say this. I wish that all were as I myself am. But each has his own gift from God, one of one kind and one of another. To the unmarried and the widows I say that it is good for them to remain single, as I am. But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion. To the married I give this charge (not I, but the Lord): the wife should not separate from her husband (but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.
