because the daughters of Manasseh received an inheritance along with his sons. The land of Gilead was allotted to the rest of the people of Manasseh.
Manasseh was itself but one half of the tribe of Joseph, and yet was divided and subdivided. 1. It was divided into two parts, one already settled on the other side Jordan, consisting of those who were the posterity of Machir, Jos 17:1.
Commenting on Joshua 17:1-6
Because the daughters of Manasseh had an inheritance among his sons,.... Which occasioned such a number of portions; the daughters of Zelophehad are meant, who descended from Manasseh: and the rest of Manasseh, some had the land of Gilead; that is, those besides the six families before expressed, namely, the two families of the Machirites and Gileadites, Num 26:29.
Jos 17:1-6 Before proceeding to the more detailed description of the inheritance, the historian thinks it necessary to observe that the Manassites received a double inheritance. This remark is introduced with the words “for he was the first-born of Joseph.” On this account, in addition to the territory already given to him in Gilead and Bashan, he received a second allotment of territory in Canaan proper.
