1 Corinthians 7:3-5
3 The husband must fulfill his duty to his wife, and likewise also the wife to her husband. 4 The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. 5 aStop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that bSatan will not tempt you because of your lack of self-control.
