1 Corinthians 7:2-3, 1 Corinthians 7:5

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 ¹fulfill his duty to his wife, and likewise also the wife to her husband.

⁵^aStop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and ¹come together again so that ^bSatan will not tempt you because of your lack of self-control.
