151 And the lot of the tribe of the children of Judah according to their families was: to the border of Edom, the wilderness of Zin, southward, in the extreme south. 2 And their southern border was from the end of the salt sea, from the tongue that turns southward; 3 and it went out south of the ascent of Akrabbim, and passed on to Zin, and went up on the south of Kadesh-barnea, and passed to Hezron, and went up toward Addar, and turned toward Karkaah, 4 and passed on to Azmon, and went out by the torrent of Egypt; and the border ended at the sea. That shall be your border southward.

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.
