And the border came down,.... In the description of the border of Judah, hereabout, it is said to go up, Jos 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 Jos 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 Jos 15:7.
