1 Corinthians 7:6-9

But this I say by way of concession, not of command. Yet I wish that all men were even as I myself am. However, each man has his own gift from God, one in this manner, 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.
