151 So this was the lot of the tribe of the children of Judah according to their families: The border of Edom at the Wilderness of Zin southward was the extreme southern boundary. 2 And their southern border began at the shore of the Salt Sea, from the bay that faces southward. 3 Then it went out to the southern side of the Ascent of Akrabbim, passed along to Zin, ascended on the south side of Kadesh Barnea, passed along to Hezron, went up to Adar, and went around to Karkaa. 4 From there it passed toward Azmon and went out to the Brook of Egypt; and the border ended at the sea. This shall be your southern border.

(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.
