1 Corinthians 7:4-6

New Matthew Bible

⁴ The wife does not have right over her own body, but the husband, and likewise the husband does not have right over his own body, but the wife. ⁵ Do not withdraw yourselves one from another, unless it be with consent for a time to give yourselves to fasting and prayer. And afterward, come again to the same thing, lest Satan tempt you through your lack of self control.

⁶ This I say by way of concession, and not of commandment.
