So Joshua took all that land, the hills, and all the south country, and all the land of Goshen, and the valley, and the plain, and the mountain of Israel, and the valley of the same; The mountain of Israel, and the valley of the same - This place has given considerable trouble to commentators; and it is not easy to assign such a meaning to the place as may appear in all respects satisfactory.
1. If we consider this verse and the 21st to have been added after the times in which the kingdoms of Israel and Judah were divided, the difficulty is at once removed.
2. The difficulty will be removed if we consider that mountain and valley are put here for mountains and valleys, and that these include all mountains and valleys which were not in the lot that fell to the tribe of Judah. Or,
3. If by mountain of Israel we understand Beth-el, where God appeared to Jacob, afterwards called Israel, and promised him the land of Canaan, a part of the difficulty will be removed. But the first opinion seems best founded; for there is incontestable evidence that several notes have been added to this book since the days of Joshua. See the preface.
