1 Corinthians 7:7-11

Yet I wish that all men were even as I myself am. However, each has his own gift from God, one in this way, and another in that.

But I say to the unmarried and to widows that it is good for them if they remain even as I.

But if they do not have self-control, let them marry; for it is better to marry than to burn with passion.

But to the married I give instructions, not I, but the Lord, that the wife is not to leave her husband

(but if she does leave, she must remain unmarried, or else be reconciled to her husband), and that the husband is not to divorce his wife.
