Deuteronomy 21:15-21

15“If a man has two wives, the one loved and 1the other 2unloved, and both the loved and the 3unloved have borne him sons, and the firstborn son belongs to the 4unloved, 16then it shall be on the day that he wills what he owns as an inheritance to his sons, he is not allowed to treat the son of the loved wife as the firstborn, 5at the expense of the son of the 6unloved, who actually is the firstborn son. 17On the contrary, he shall acknowledge the firstborn, the son of the 7unloved wife, by giving him a double 8portion of everything that 9he owns, for he was the 10beginning of his 11strength; 12to him belongs the right of the firstborn.

18“If any person has a stubborn and rebellious son who does 13not obey his father or his mother, and when they discipline him, he does not listen to them, 19then his father and mother shall seize him, and bring him out to the elders of his city 14at the gateway of his hometown. 20And they shall say to the elders of his city, ‘This son of ours is stubborn and rebellious; he does not obey us, he is thoughtless and given to drinking.’ 2115Then all the men of his city shall stone him to death; so 16you shall eliminate the evil from your midst, and 17all Israel will hear about it and fear.
