and the border went up to Beth Hoglah, and passed along by the north of Beth Arabah; and the border went up to the stone of Bohan the son of Reuben;
      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, Joshua 15:5; Joshua 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 Joshua 15:1-4; Joshua 15:34; Joshua 15:3-5. 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,Obadiah 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 (Joshua 15:6; Joshua 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 (Joshua 15:7; Joshua 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 (Joshua 15:8; Joshua 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 (Joshua 15:12; Joshua 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.
