14 It shall be, if you have no delight in her, then you shall let her go where she will; but you shall not sell her at all for money, you shall not deal with her as a slave, because you have humbled her.

Matthew Henry's Commentary on Deuteronomy 21:14

Commentary on Deuteronomy 21:10-14

(Read Deuteronomy 21:10-14)
