1 Corinthians 7:6-9

But this I say by way of concession, not of commandment. Yet I would that all men were even as I myself. Howbeit each man hath his own gift from God, one after this manner, and another after that. But I say to the unmarried and to widows, It is good for them if they abide even as I. But if they have not continency, let them marry: for it is better to marry than to burn.
