Manasseh had in Issachar and in Asher — As Ephraim had some cities in the tribe of Manasseh, and as it was not unusual, when the place allotted to any tribe was too narrow for it, and the next too large, to give away part from the larger to the less portion; nay, sometimes one whole tribe was taken into another; as Simeon's was into Judah's portion, when it was found too large for Judah. Inhabitants of Dor — Not the places only, but the people; whom they spared and used for servants. Three countries — The words may be rendered, the third part of that country; and so the meaning may be, that the cities and towns here mentioned are a third part of that country, that is, of that part of Issachar's and Asher's portion, in which those places lay.
