Deuteronomy 21:15-21

15Suppose a man has two wives, one whom he loves more than the other, and they both bear him sons, with the firstborn being the child of the less loved wife.

16In the day he divides his inheritance he must not appoint as firstborn the son of the favorite wife in place of the other wife’s son who is actually the firstborn.

17Rather, he must acknowledge the son of the less loved wife as firstborn and give him the double portion of all he has, for that son is the beginning of his father’s procreative power – to him should go the right of the firstborn.

18If a person has a stubborn, rebellious son who pays no attention to his father or mother, and they discipline him to no avail,

19his father and mother must seize him and bring him to the elders at the gate of his city.

20They must declare to the elders of his city, “Our son is stubborn and rebellious and pays no attention to what we say – he is a glutton and drunkard.”

21Then all the men of his city must stone him to death. In this way you will purge out wickedness from among you, and all Israel will hear about it and be afraid.
