Judah and Joseph were the two sons of Jacob on whom Reuben's forfeited birth-right devolved. Judah had the dominion entailed on him, and Joseph the double portion, and therefore these two tribes were first seated, Judah in the southern part of the land of Canaan and Joseph in the northern part, and on them the other seven did attend, and had their respective lots as appurtenances to these two; the lots of Benjamin, Simeon, and Dan, were appendant to Judah, and those of Issachar and Zebulun, Naphtali and Asher, to Joseph. These two were first set up to be provided for, it should seem, before there was such an exact survey of the land as we find afterwards, Jos 18:9. It is probable that the most considerable parts of the northern and southern countries, and those that lay nearest to Gilgal, and which the people were best acquainted with, were first put into two portions, and the lot was cast upon them between these two principal tribes, of the one of which Joshua was, and of the other Caleb, who was the first commissioner in this writ of partition; and, by the decision of that lot, the southern country, of which we have an account in this chapter, fell to Judah, and the northern, of which we have an account in the two following chapters, to Joseph. And when this was done there was a more equal dividend (either in quantity or quality) of the remainder among the seven tribes. And this, probably, was intended in that general rule which was given concerning this partition (Num 33:54), to the more you shall give the more inheritance, and to the fewer you shall give the less, and every man's inheritance shall be where his lot falleth; that is, "You shall appoint two greater portions which shall be determined by lot to those more numerous tribes of Judah and Joseph, and then the rest shall be less portions to be allotted to the less numerous tribes." The former was done in Gilgal, the latter in Shiloh.

In these verses, we have the borders of the lot of Judah, which, as the rest, is said to be by their families, that is, with an eye to the number of their families. And it intimates that Joshua and Eleazar, and the rest of the commissioners, when they had by lot given each tribe its portion, did afterwards (it is probable by lot likewise) subdivide those larger portions, and assign to each family its inheritance, and then to each household, which would be better done by this supreme authority, and be apt to give less disgust than if it had been left to the inferior magistrates of each tribe to make that distribution. The borders of this tribe are here largely fixed, yet not unalterably, for a good deal of that which lies within these bounds was afterwards assigned to the lots of Simeon and Dan. 1. The eastern border was all, and only, the Salt Sea, Jos 15:5. Every sea is salt, but this was of an extraordinary and more than natural saltness, the effects of that fire and brimstone with which Sodom and Gomorrah were destroyed in Abraham's time, whose ruins lie buried in the bottom of this dead water, which never either was moved itself or had any living thing in it. 2. The southern border was that of the land of Canaan in general, as will appear by comparing Jos 15:1-4 with Num 34:3-5. So that this powerful and warlike tribe of Judah guarded the frontiers of the whole land, on that side which lay towards their old sworn enemies (though their two fathers were twin-brethren), the Edomites. Our Lord therefore, who sprang out of Judah, and whose the kingdom is, shall judge the mount of Esau, Oba 1:21. 3. The northern border divided it from the lot of Benjamin. In this, mention is made of the stone of Bohan a Reubenite (Jos 15:6), who probably was a great commander of those forces of Reuben that came over Jordan, and died in the camp at Gilgal, and was buried not far off under this stone. The valley of Achor likewise lies upon this border (Jos 15:7), to remind the men of Judah of the trouble which Achan, one of their tribe, gave to the congregation of Israel, that they might not be too much lifted up with their services. This northern line touched closely upon Jerusalem (Jos 15:8), so closely as to include in the lot of this tribe Mount Zion and Mount Moriah, though the greater part of the city lay in the lot of Benjamin. 4. The west border went near to the great sea at first (Jos 15:12), but afterwards the lot of the tribe of Dan took off a good part of Judah's lot on that side; for the lot was only to determine between Judah and Joseph, which should have the north and which the south, and not immovably to fix the border of either. Judah's inheritance had its boundaries determined. Though it was a powerful warlike tribe, and had a great interest in the other tribes, yet they must not therefore be left to their own choice, to enlarge their possessions at pleasure, but must live so as that their neighbours might live by them. Those that are placed high yet must not think to be placed alone in the midst of the earth.

Maaleh-acrabbim - The ascent of the Mount of Scorpions, probably so called from the multitude of those animals found in that place.

Kadesh-barnea - This place was called Enmishpat, Gen 14:7. It was on the edge of the wilderness of Paran, and about twenty-four miles from Hebron. Here Miriam, the sister of Moses and Aaron, died; and here Moses and Aaron rebelled against the Lord; hence the place was called Meribah-Kadesh, or the contention of Kadesh.

Karkaa - Supposed to be the Coracea of Ptolemy, in Arabia Petraea. - Calmet.

And it went out to the south side of Maalehacrabbim,.... Or the ascent of Akrabbim, as it is called; see Gill on Num 34:4,

and passed along to Zin, and ascended upon the south side unto Kadeshbarnea; which perfectly agrees with the southern border of the land, as described in Num 34:4,

and passed along to Hezron, and went up to Adar; which two places being near to one another, as is very likely, are put together, as if one place, and called Hazaraddar, Num 34:4; and mention is made of Hezron, which is Hazor, Jos 15:25; but not of Adar:

and fetched a compass to Karkaa; which Jerom (w) calls Acchara, a village in the wilderness; and if the same with Carcaria, it was according to him a day's journey from Petra in Idumea; but that is not likely; see Jdg 8:10.

(w) De loc. Heb. fol. 88. E. 90. C.

Maaleh-akrabbim--Hebrew, "the ascent of scorpions"; a pass in the "bald mountain" (see on Jos 11:17), probably much infested by these venomous reptiles.
