7 The border then ascended to Debir from Trouble Valley and turned north toward Gilgal, which lies opposite Red Pass, just south of the gorge. The border then followed the Waters of En Shemesh and ended at En Rogel. 8 The border followed the Valley of Ben Hinnom along the southern slope of the Jebusite ridge (that is, Jerusalem). It ascended to the top of the mountain opposite Hinnom Valley on the west, at the northern end of Rephaim Valley; 9 the border then took a turn at the top of the mountain to the spring, the Waters of Nephtoah, and followed the valley out to Mount Ephron, turned toward Baalah (that is, Kiriath Jearim), 10 took another turn west of Baalah to Mount Seir, curved around to the northern shoulder of Mount Jearim (that is, Kesalon), descended to Beth Shemesh, and crossed to Timnah.

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.
