How can Israel's boundaries described in Numbers 34:1-15 be compared to Israel's boundaries today?

The challenge to answering this question lies in dealing
with all the cities named in Numbers that are no longer in existence or that have had
name changes beyond recognition.

The Wilderness of Zin is
the area known today as the Negev;the southern border starts at the southwest end of the
Dead Sea (Salt Sea) across from Edom, which can be seen as roughly the southwestern
border between Israel and Jordan. Kadesh-barnea is known today as Ain el Qiderirat and
is located just across the border into the Sinai Peninsula. The brook of Egypt is now
known as Wadi el Arish. The Great Sea is easy - the Mediterranean
Sea.

Moving north along the western boundary of the
Mediterranean, Hamah (Hamath) is to the east, inland from the coast in what is now
Syria. I am not able to identify the other towns marking the eastern border, but it ends
back at the Dead Sea. So the actual territory promised by God to the Hebrew people
stretched much further north and south along the Mediterranean
coastline.
