10 If he takes another wife to himself, he shall not diminish her food, her clothing, and her marital rights.
Exodus 21:10 Cross References - VIN
1 Now for the matters you wrote about: It is good to abstain from sexual relations. 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 has not power over her body, but the husband; and in the same way the husband has not power over his body, but the wife. 5 Do not deprive one another, except by agreement for a time, so that you may devote yourselves to prayer, and then come together again so that Satan will not tempt you because of your lack of self-control. 6 I say this as a concession, not as a command.
