1 Corinthians 7:4-6

American Standard Version

⁴ The wife hath not power over her own body, but the husband: and likewise also the husband hath not power over his own body, but the wife. ⁵ Defraud ye not one the other, except it be by consent for a season, that ye may give yourselves unto prayer, and may be together again, that Satan tempt you not because of your incontinency. ⁶ But this I say by way of concession, not of commandment.
