1 Corinthians 7:2-5

2But because of sexual immoralities, each man is to have his own wife, and each woman is to have her own husband.

3The husband must fulfill his duty to his wife, and likewise the wife also to her husband.

4The wife does not have authority over her own body, but the husband does; and likewise the husband also does not have authority over his own body, but the wife does.

512Stop depriving one another, except by agreement for a time so that you may devote yourselves to prayer, and 3come together again so that 4Satan will not tempt you because of your lack of self-control.
