1 Corinthians 7:2-16

2Nevertheless, to avoid immorality, let every man have his own wife, and let every woman have her own husband. 3Let the husband render to the wife her due benevolence: and likewise also the wife to the husband. 4The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife. 5Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan may not tempt you for your lack of self-control. 6But I speak this by permission, and not as a commandment. 7For I would that all men were as I myself. But every man hath his proper gift from God, one after this manner, and another after that. 8I say therefore to the unmarried and widows, It is good for them if they remain even as I. 9But if they cannot control themselves, let them marry: for it is better to marry than to burn.

10And to the married I command, yet not I, but the Lord, Let not the wife depart from her husband: 11But if she shall depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife. 12But to the rest I speak, not the Lord: If any brother hath a wife that believeth not, and she is pleased to dwell with him, let him not put her away. 13And the woman who hath an husband that believeth not, and if he is pleased to dwell with her, let her not leave him. 14For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy. 15But if the unbelieving departeth, let him depart. A brother or a sister is not under bondage in such cases : but God hath called us to peace.1 16For how knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?2
