Adam Clarke Bible Commentary

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.
