Joshua 15:1

The allotment for the tribe of the people of Judah according to their clans reached southward to the boundary of Edom , to the wilderness of Zin at the farthest south .

The allotment for the tribe of Judah, according to its clans, extended down to the territory of Edom, to the Desert of Zin in the extreme south.

This 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.
