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.

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.
