יהושע, פרק י״ז, פסוק י״א

The division of the land of Israel involved unique territorial arrangements, sometimes resulting in one tribe holding enclaves within the borders of another. The tribe of Manasseh was granted ownership over specific central cities, along with their surrounding satellite towns, that were geographically situated inside the neighboring territories of Issachar and Asher [מצודת דוד, מלבי״ם, ביאור שטיינזלץ].

These designated areas are categorized into three districts or regions. The primary approach among commentators is that the various cities granted to Manasseh were spread across three distinct regions [מצודת דוד, ביאור שטיינזלץ], which were geographically linked to form one large, continuous territory [מלבי״ם]. Taking a different approach, another perspective limits this regional description entirely to the city of Dor and its immediate surroundings, noting that elsewhere, the concept of a district is directly associated exclusively with Dor [רש״י].
