יהושע יח:ה פירוש: רש״י

And they will divide it into seven parts. Including that which was already conquered and that which was destined to be conquered.

Yehudah will remain at his boundary in the south— of Eretz Yisroel, for there fell to his lot the entire southern boundary.

And the house of Yoseif—in the north. The north of the land already conquered. There is however much more to be conquered: the side of the boundary from Baal-gad to Levo-chamos which is near Hor hoHor in the northern boundary. The seven tribes will divide [the land] between Yehudah and Yoseif, and [the land] which remains to be conquered.
