7 Then the border went up toward Debir from the Valley of Achor, and it turned northward toward Gilgal, which is before the Ascent of Adummim, which is on the south side of the valley. The border continued toward the waters of En Shemesh and ended at En Rogel. 8 And the border went up by the Valley of the Son of Hinnom to the southern slope of the Jebusite city (which is Jerusalem). The border went up to the top of the mountain that lies before the Valley of Hinnom westward, which is at the end of the Valley of Rephaim northward. 9 Then the border went around from the top of the hill to the fountain of the water of Nephtoah, and extended to the cities of Mount Ephron. And the border went around to Baalah (which is Kirjath Jearim). 10 Then the border turned westward from Baalah to Mount Seir, passed along to the side of Mount Jearim on the north (which is Chesalon), went down to Beth Shemesh, and passed on to Timnah.

Matthew Henry's Commentary on Joshua 15:7-10

Commentary on Joshua 15:1-12

(Read Joshua 15:1-12)

Joshua allotted to Judah, Ephraim, and the half of Manasseh, their inheritances before they left Gilgal. Afterwards removing to Shiloh, another survey was made, and the other tribes had their portion assigned. In due time all God's people are settled.
