Deuteronomy 21:14-16

Common English Bible

¹⁴ But if you aren’t pleased with her, you must send her away as she wishes. You are not allowed to sell her for money or treat her as a slave because you have humiliated her.

Right of the oldest son

¹⁵ Now suppose a man has two wives—one of them loved and the other unloved. Both wives bear children, but the oldest male is the unloved wife’s child. ¹⁶ On the day when the man decides what will go to each of his children as an inheritance, he isn’t allowed to treat his loved wife’s son as the oldest male rather than his unloved wife’s son, who is the real oldest male.
