Joshua 18:5

Into seven parts Their business was to divide the country into seven portions of equal extent or worth, and leave God to appoint which portion should fall to each tribe; who could have no reason to complain when the division was made by themselves. Indeed, 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, and when they pleased they might take possession of it. 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.
