Joshua 15:1-4

1This then was the lot of the tribe of the children of Judah by their families; even to the border of Edom the wilderness of Zin southward was the uttermost part of the south coast.

2And their south border was from the shore of the salt sea, from the bay that looketh southward:1

3And it went out to the south side to Maaleh–acrabbim, and passed along to Zin, and ascended up on the south side unto Kadesh–barnea, and passed along to Hezron, and went up to Adar, and fetched a compass to Karkaa:2

4From thence it passed toward Azmon, and went out unto the river of Egypt; and the goings out of that coast were at the sea: this shall be your south coast.
