So the children of Joseph, Manasseh and Ephraim, (c) took their inheritance.
(c) Severally, first Ephraim, and then Manasseh.
So the children of Joseph, Manasseh and Ephraim, took their inheritance. As it fell to them by the lot; by Manasseh is meant the half tribe of Manasseh, one half of that tribe having been settled by Moses on the other side Jordan; and next follows an account of the borders of the inheritance of Ephraim in particular, as that of the half tribe of Manasseh is given in Joshua 17:1.
The territory commencing at the boundary lines mentioned was allotted to Ephraim and Manasseh as their inheritance.
Manasseh - That is, half Manasseh. Their inheritance - Their several portions which here follow. It is said, they took their inheritance, which also Judah had done before them, because the tribes of Judah and Joseph did take their inheritances before the rest; and it was fit they should do so, for the security of the main camp, and the body of the people which were at Gilgal, Joshua 18:5.
