15 “If a man has two wives, ⁱthe one loved and the other unloved, and both the loved and the unloved have borne him children, and if the firstborn son belongs to the unloved,¹ 16 then on the day when ^jhe assigns his possessions as an inheritance to his sons, he may not treat the son of the loved as the firstborn in preference to the son of the unloved, who is the firstborn, 17 but he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is ^kthe firstfruits of his strength. ^lThe right of the firstborn is his.
