1 Corinthians 7:2-4

New Century Version

² But because sexual sin is a danger, each man should have his own wife, and each woman should have her own husband. ³ The husband should give his wife all that he owes her as his wife. And the wife should give her husband all that she owes him as her husband. ⁴ The wife does not have full rights over her own body; her husband shares them. And the husband does not have full rights over his own body; his wife shares them.
