1 Corinthians 7:6-11

But I speak this by permission, and not of commandment. For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that. I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn. And unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband: but and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife.
