151 The allotment for the clans of the tribe of Judah reached southward to the border of Edom, as far south as the wilderness of Zin. 2 The southern boundary began at the south bay of the Dead Sea, 3 ran south of Scorpion Pass into the wilderness of Zin, and then went south of Kadesh-barnea to Hezron. Then it went up to Addar, where it turned toward Karka. 4 From there it passed to Azmon until it finally reached the Brook of Egypt, which it followed to the Mediterranean Sea. This was their southern boundary.

(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.
