1 Corinthians 7:2-6

2but on account of fornications, let each have his own wife, and each [woman] have her own husband.

3Let the husband render her due to the wife, and in like manner the wife to the husband.

4The wife has not authority over her own body, but the husband: in like manner also the husband has not authority over his own body, but the wife.

5Defraud not one another, unless, it may be, by consent for a time, that ye may devote yourselves to prayer, and again be together, that Satan tempt you not because of your incontinency.

6But this I say, as consenting [to], not as commanding [it].
