1Now for the matters you wrote about: It is good for a man not to marry.[1] 2But since there is so much immorality, each man should have his own wife, and each woman her own husband. 3The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 4The wife's body does not belong to her alone but also to her husband. In the same way, the husband's body does not belong to him alone but also to his wife. 5Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. 6I say this as a concession, not as a command. 7I wish that all men were as I am. But each man has his own gift from God; one has this gift, another has that. 
8Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I am. 9But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion. 
10To the married I give this command (not I, but the Lord): A wife must not separate from her husband. 11But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
