1 Corinthians 7:2-4

BSB(i) 2 But because there is so much sexual immorality, each man should have his own wife, and each woman her own husband. 3 The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 4 The wife does not have authority over her own body, but the husband. Likewise the husband does not have authority over his own body, but the wife.
