דברי הימים א, פרק ו׳, פסוק מ״ז

The allocation of land to the Levites involved assigning thirteen specific cities to the descendants of Gershom. These cities were drawn from the territories of the northern and Transjordanian tribes, specifically Issachar, Asher, Naphtali, and Manasseh.

The distribution was organized strictly around their family structures. Unlike the descendants of Kohath, whose land grants were split and scattered, all the families of Gershom were grouped together in this single, unified distribution [רלב״ג]. Practically, this method of settlement meant that the cities were divided so that each distinct family unit lived independently in its own separate residential area [מצודת דוד].

When drawing from the territory of Manasseh, the cities were specifically selected from the region of the Bashan. This clarifies that the land came from the half-tribe of Manasseh located east of the Jordan River. This geographical distinction separates them from the other half-tribe of Manasseh situated within the main borders of the Land of Israel, which instead provided cities for the descendants of Kohath [מצודת דוד, ביאור שטיינזלץ].
