Deuteronomy 21:14 NASB
It shall be, if you are not pleased with her, then you shall let her go wherever she wishes; but you shall certainly not sell her for money, you shall not mistreat her, because you have humbled her.
Why does God allow a man to let his wife go if he isn’t pleased with her? I know these wives were taken among captives but why does that make any difference once they’re bound as husband/wife? (I am asking in the context of other laws God gave regarding marriage in the Old Testament, not in the context of the New Testament).
