Joshua 18:5

Judah shall abide - on the south, and the house of Joseph - on the north - Joshua does not mean that the tribe of Judah occupied the south, and the tribe of Ephraim and Manasseh the north of the promised land; this was not the fact: but being now at Shiloh, a considerable way in the territory of Ephraim, and not far from that of Judah, he speaks of them in relation to the place in which he then was. Calmet considers him as thus addressing the deputies: "Go and examine the whole of the country which remains yet to be possessed; do not take into consideration the tribe of Judah, which is on the south, nor the tribe of Ephraim, which is on the north of where we now are, but carefully divide the remaining land which is not occupied by these tribes into seven equal parts." This makes a very good sense, and frees the place from embarrassment.

18:5 Seven parts - Which were of equal extent or worth: for no tribe was so great, but one of these parts in its full extent would abundantly suffice them; and there was no reason why the portions should be greater or less according as the tribes at present were more or fewer in number, because of the various changes which happened therein successively; it being usual for one tribe to be more numerous than another in one age, which was fewer in the next. And if the several tribes had increased more, and not diminished their numbers by their sins, they might have sent forth colonies, and taken any part of the land, even as far as Euphrates, all which the Lord of the whole earth had given them a right to, which when they pleased they might take possession of. Judah shall abide on the south - They shall not be disturbed in their possession, but shall keep it, except some part of it shall be adjudged to another tribe. Joseph on the north - In respect of Judah, not of the whole land; for divers other tribes were more northern than they.
