Joshua 16:4 - John Gill's Exposition of the Entire Bible

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.
