Deuteronomy 21:15-21

15A man might have two wives and love one but not the other. Both wives might have children, and the firstborn son might belong to the wife that the man doesn’t love.

16When the day comes for the father to give his sons their inheritance, he can’t treat the son of the wife he loves as if that son were the firstborn. This would show a total disregard for the real firstborn (the son of the wife he doesn’t love).

17Instead, he must recognize the son of the wife he doesn’t love as the firstborn. He must give that son a double portion of whatever he owns. That son is the very first son he had. The rights of the firstborn son are his.

18Parents might have a stubborn and rebellious son who doesn’t obey them. Even though they punish him, he still won’t listen to them.

19His father and mother must take him to the leaders of the city at the city gate.

20They will say to the leaders of the city, “This son of ours is stubborn and rebellious. He won’t obey us. He eats too much and is a drunk.”

21All the men of the city should stone him to death. You must get rid of this evil. When all Israel hears about it, they will be afraid.
