Deuteronomy 21:15-17

International Standard Version

Preferential Treatment Prohibited

¹⁵ “If a man has two wives where one is loved but the other is unloved, and both^[a] of them bear him sons, but the firstborn is the son of the unloved wife, ¹⁶ then when he bequeaths his possessions to his sons, he must not give preference to the firstborn of the beloved wife over the firstborn of the unloved wife. ¹⁷ Instead, he must acknowledge the firstborn of the unloved wife by giving him double of everything he owns, because he is really the first fruit of his father’s^[b] strength. The right of the firstborn belongs to him.”
