Deuteronomy 21:15-21

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

16then it shall be, on the day he bequeaths his possessions to his sons, that he must not bestow firstborn status on the son of the loved wife in preference to the son of the unloved, the true firstborn.

17But he shall acknowledge the son of the unloved wife as the firstborn by giving him a double portion of all that he has, for he is the beginning of his strength; the right of the firstborn is his.

18“If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and who, when they have chastened him, will not heed them,

19then his father and his mother shall take hold of him and bring him out to the elders of his city, to the gate of his city.

20And they shall say to the elders of his city, ‘This son of ours is stubborn and rebellious; he will not obey our voice; he is a glutton and a drunkard.’

21Then all the men of his city shall stone him to death with stones; so you shall put away the evil from among you, and all Israel shall hear and fear.
