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.

The valley of Achor - Debir mentioned in this verse is unknown. The valley of Achor had its name from the punishment of Achan. See the account, Jos 7:24 (note), etc.

En-shemesh - The fountain of the sun; it was eastward of Jerusalem, on the confines of Judah and Benjamin.

And the border went up towards Debir,.... This was neither the Debir in the tribe of Gad, on the other side Jordan, Jos 13:26; nor that in the tribe of Judah near Hebron, Jos 15:15; but a third city of that name, and was not far from Jericho:

from the valley of Achor; where Achan was put to death, and had its name from thence; which, according to Jarchi, lay between the stone of Bohan and Debir:

and so northward, looking towards Gilgal; not the place where Israel were encamped when this lot was made, but it seems to be the same that is called Geliloth, Jos 18:17,

that is, the going up to Adummim; which, Jerom says (c), was formerly a little village, now in ruins, in the lot of the tribe of Judah, which place is called to this day Maledomim; and by the Greeks "the ascent of the red ones", because of the blood which was there frequently shed by thieves: it lies on the borders of Judah and Benjamin, as you go from Jerusalem to Jericho, where there is a garrison of soldiers for the help of travellers, and is supposed to be the place where the man fell among thieves in his way from the one to the other, Luk 10:30. It was four miles distant from Jericho to the west, according to Adrichomius (d), and was a mountain, and part of the mountains of Engaddi:

which is on the south side of the river; which some take to be the brook Kidron; but that is not very likely, being too near Jerusalem for this place: it may be rendered "the valley", so Jarchi, either the valley of Achor, before mentioned, or however a valley that ran along by the mount or ascent of Adummim, which lay to the south of it:

and the border passed to the waters of Enshemesh: or the "fountain of the sun"; but of it we have no account what and where it was. It might be so called, because dedicated to the sun by the idolatrous Canaanites, or because of the sun's influence on the waters of it. Our city, Bath, is, by Antoninus (e), called "aquae solis", the waters of the sun; though there is a fountain in Cyrene, so called, for a reason just the reverse, it being, as Mela (f) and Pliny (g) affirm, hottest the middle of the night, and then grows cooler by little and little; and when it is light is cold, and when the sun is risen is colder still, and at noon exceeding cold; and, according to Vossius (h), it is the same with the fountain of Jupiter Ammon; and so it appears to be from Herodotus (i), by whom it is also called the "fountain of the sun", and which he places in Thebes, though Pliny distinguishes them:

and the goings out thereof were at Enrogel; which signifies "the fountain of the fuller"; so the Targum renders it, and probably was a fountain where fullers cleansed their clothes; and was called Rogel, as Jarchi and Kimchi say, because they used to tread them with their feet when they washed them. This was a place near Jerusalem, as appears from Kg1 1:9; near to which perhaps was the fuller's monument, at the corner tower of Jerusalem, Josephus (k) speaks of, as there was also a place not far from it called the fuller's field, Isa 7:3; according to Bunting (l), it had its name from travellers washing their feet here.

Achor--(see on Jos 7:26).

Adummim--a rising ground in the wilderness of Jericho, on the south of the little brook that flowed near Jericho (Jos 16:1).

En-shemesh--"the fountain of the sun"; "either the present well of the apostle, below Bethany, on the road to Jericho, or the fountain near to St. Saba" [ROBINSON].

En-rogel--"the fuller's fountain," on the southeast of Jerusalem, below the spot where the valleys of Jehoshaphat and Hinnom unite.
