Deuteronomy 21:17-19

Common English Bible

¹⁷ Instead, he must acknowledge the unloved wife’s son as the oldest male, giving to him two-thirds of everything that he owns, because that son is the earliest produce of his physical power. The oldest male’s rights belong to that son.

Rebellious children

¹⁸ Now if someone has a consistently stubborn and rebellious child, who refuses to listen to their father and mother—even when the parents discipline him, he won’t listen to them— ¹⁹ the father and mother will take the son before the elders of that city at its gates.
