1 Corinthians 7:4-5

King James Version

⁴ The 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.

⁵ Defraud 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 tempt you not for your incontinency.
