'Southern' in the Bible

your southern region shall be from the Wilderness of Zin along the side of Edom, and your southern boundary from the end of the Salt (Dead) Sea eastward.

Now the lot (allotment) for the tribe of the sons of Judah according to their families reached [southward to] the border of Edom, southward to the wilderness of Zin at its most southern part.

It continued along to Azmon and proceeded to the Brook of Egypt (Wadi el-Arish), and the border ended at the [Mediterranean] sea. This was their southern border.

Then the border went up by the Valley of Ben-hinnom (son of Hinnom) at the southern slope of the Jebusite [city] (that is, Jerusalem); and the border went up to the top of the mountain that lies before the Valley of Hinnom to the west, which is at the northern end of the Valley of Rephaim.

The southern side was from the edge of Kiriath-jearim, and the border went on westward and went to the source of the waters of Nephtoah.

The border continued along to the north of the slope of Beth-hoglah; and the border ended at the northern bay of the Salt (Dead) Sea, at the south end of the Jordan. This was the southern border.

behold (hear this), therefore, I am against you and against your rivers (the Nile, its tributaries), and I will make the land of Egypt a complete waste and a desolation, from [northern] Migdol to [southern] Syene, even as far as the border of Ethiopia (Cush).
