Deuteronomy 21:14-16

Amplified Bible, Classic Edition

¹⁴ And if you have no delight in her, then you shall let her go absolutely free. You shall not sell her at all for money; you shall not deal with her as a slave or a servant, because you have humbled her.

¹⁵ If a man has two wives, one loved and the other disliked, and they both have borne him children, and if the firstborn son is the son of the one who is disliked,

¹⁶ Then on the day when he wills his possessions to his sons, he shall not put the firstborn of his loved wife in place of the [actual] firstborn of the disliked wife—her firstborn being older.
