This then was the lot of the tribe of the children of Judah by their families,.... The land of Canaan was divided by lot to the several tribes, and the tribe of Judah had its lot first; of the manner of casting lots; see Gill on Num 26:55; It seems as if the lot was first cast for the tribes of Judah and Joseph, when the former had the southern, and the latter the northern part of the land for their portion, which was done in Gilgal; after this lots were cast in Shiloh for the other seven tribes, who had the land divided among them, which lay between Judah and Joseph, or between the southern and northern parts of the land, see Jos 18:1, &c. and it seems that not only the land was divided to the tribes by lot, but that the portion of land which belonged to each tribe was divided in the same way to the several families and households belonging thereunto; as is here suggested, with respect to the tribe of Judah, whose lot reached even to the border of Edom; or Idumea, which lay to the south of the land of Canaan: the wilderness of Zin southward was the uttermost part of the south coast; the same with Kadesh, and lay upon the borders of Edom; see Num 33:36.
