Jewish History: Tribal Boundaries
During the period of the Israelite repatriation to the Land of Israel (c. 1273–1245 BCE), the 12 tribes—Reuven, Shimon, Levi, Judah, Yisakhar, Zvulun, Dan, Naphtali, Gad, Asher, Joseph (Ephraim and Menasheh), and Benjamin—were allocated lands on both sides of the Jordan River and the Salt (Dead) Sea. These allocations were typically discrete territories; owing to its unique sacerdotal duties, however, the tribe of Levi did not receive contiguous territory, but rather 48 cities—including 13 Kohanic (priestly) cities and six cities of refuge—throughout the Land of Israel.
The tribal territories are demarcated in the Tanakh (Hebrew Bible), particularly in the books of Numbers (32, 34–35) and Joshua (13–19). As with its several and sundry descriptions of the borders of the Land of Israel (maximal, medial, and minimal), Scripture is often imprecise with its delineations of the tribal boundaries: the descriptions are rarely straightforward and typically comprise a series of cities and towns, along with their immediate environs, belonging to the respective tribes.
The subject is further complicated for a number of reasons, including: certain tribes possessed loci within the territories of other tribes (e.g., Menasheh in Asher and Naphtali, Ephraim in Menasheh, Gad in Reuven); the allotments were official inheritances not always fulfilled in practice due to the ongoing presence of existent Canaanite populations; the Neo-Philistine invasion of the southern Levant (c. 1175 BCE) carved out from the tribal territory of Judah the coastal region of Philistia, a pentapolis of five city-states (Ashdod, Ashkelon, Gaza, Gath, Ekron); part of the tribe of Dan (600 Danites girded with weapons) migrated early in the era of the Judges (c. 1228–1020 BCE) northeastward toward the sources of the Jordan River in the Beit Rehov Valley in Upper Galilee; following the division of the United Monarchy (931 BCE), part of the tribe of Shimon apparently migrated northward to the Kingdom of Israel (though many of these Shimonites subsequently returned) and, later, another part migrated to Gdor (Gerar?) and southeastward to Mount Seir (where 500 Shimonites struck down remaining Amalekites); over the course of time, certain border towns shifted from one tribe to another (e.g., Beit El and Jerusalem, both formerly within Benjamin, were later absorbed into Ephraim and Judah, respectively), and indeed in some instances an entire tribal territory was incorporated into that of another (e.g., Shimon and Benjamin into neighboring Judah); and some modern identifications of biblical sites (e.g., the Yiftah-el Valley, Ramot-Gilad) germane to the tribal boundaries remain either tentative or elusive.

What, then, is the relation between the tribal territories collectively and the several sets of borders of the Land of Israel? In point of fact, the tribal territories most closely conform to the minimal borders of the Land of Israel, namely “from Dan to Be’ersheva” or “from Be’ersheva to Dan”; interestingly, they also share much in common with the prophet Ezekiel’s envisioned borders (minus, apparently, much of Transjordan and the eastern tableland).
Tribal Israel evolved into the United Monarchy of Israel (1030–931 BCE) that consolidated the nation. Today, the State of Israel possesses much but not all of the tribal territories: most of eastern Judah, Benjamin, Ephraim, and western Menasheh remain disputed and predominantly inhabited by Palestinian Arabs, while the Transjordanian and translacustrine territories of Gad and Reuven remain occupied by Jordan, and eastern Menasheh (excepting the western Golan) by Syria and Jordan.
