And the border came down
 In the description of the border of Judah, hereabout, it is said to go up, ( Joshua 15:5 ) ; because there, as Jarchi observes, the measure was from east to west, but here from west to east: 
 to the end of the mountain that [lieth] before the valley of the son
 of Hinnom;
 this south border of Benjamin is the same with the north border of Judah; and the same places are mentioned in the description of the one as of the other, see ( Joshua 15:8 ) . The mountain is Mount Moriah, 
 [and] which [is] in the valley of the giants on the north;
 on the north of the valley of Rephaim: 
 and descended to the valley of Hinnom;
 the border from the end of Mount Moriah to that valley: 
 to the side of Jebusi on the south;
 to the south side of Jerusalem, having that city on the south; 
and descended to Enrogel; of which (See Gill on Joshua 15:7).
