I Corinthians 7:6-9

But I say this as a concession, not as a commandment. For I wish that all men were even as I myself. But each one has his own gift from God, one in this manner and another in that. But I say to the unmarried and to the widows: It is good for them if they remain even as I am; but if they cannot exercise self-control, let them marry. For it is better to marry than to burn with passion.
