1 Corinthians 7:1-11

Now as to the matters of which you wrote: It is good (beneficial, advantageous) for a man not to touch a woman [outside marriage]. But because of [the temptation to participate in] sexual immorality, let each man have his own wife, and let each woman have her own husband. The husband must fulfill his [marital] duty to his wife [with good will and kindness], and likewise the wife to her husband. The wife does not have [exclusive] authority over her own body, but the husband shares with her; and likewise the husband does not have [exclusive] authority over his body, but the wife shares with him. Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control. But I am saying this as a concession, not as a command. I wish that all the people were as I am; but each person has his own gift from God, one of this kind and one of that. But I say to the unmarried and to the widows, [that as a practical matter] it is good if they remain [single and entirely devoted to the Lord] as I am. But if they do not have [sufficient] self-control, they should marry; for it is better to marry than to burn with passion. But to the married [believers] I give instructions—not I, but the Lord—that the wife is not to separate from her husband, (but even if she does leave him, let her remain single or else be reconciled to her husband) and that the husband should not leave his wife.
