15 If a man has two wives and loves one more than the other, but they’ve both given birth to sons for him but the oldest son is from the wife he dislikes, 16 then when he assigns his inheritance to his sons, he mustn’t favour the son of the favourite wife over that eldest son. 17 Instead, he must acknowledge the son of the wife he dislikes, and given him double of everything, because that son is the beginning of his strength, and the largest share belongs to him.
