This then was the lot of the tribe of the children of Judah according to their families; even to the border of Edom, the wilderness of Zin southward was the farthest part of the south border.

Sin, or Sina, (ver. 3,) bordering upon Idumea, where the city of Cades-barne was situated, Numbers xiii. 22. It is now impossible to ascertain the precise situation of all the place mentioned in Scripture, as the land of Chanaan has been subject to so many changes. But this inconvenience attends all ancient geography. If those who attempt to unravel such labyrinths in profane authors, deserve praise, much more do those who do their utmost to explain the difficulties of sacred history. It was once very necessary to have the limits of the tribes marked out with precision, that, at the return from captivity, they might occupy their own. Now we may be satisfied if we can point out some of the places of the greatest importance. The limits of the tribe of Juda are specified with particular care, on account of the dignity and power of that tribe, which was to give kings to all the land, and a Messias to the world, as well as to preserve the true religion. The greatest part of the southern regions of Chanaan fell to their share, from the Dead Sea, by Idumea, to the Nile, and as far north as Jerusalem and the torrent of Cedron. (Calmet)
