Neither did Manasseh drive out the inhabitants of Beth-shean and her towns, nor Taanach and her towns, nor the inhabitants of Dor and her towns, nor the inhabitants of Ibleam and her towns, nor the inhabitants of Megiddo and her towns: but the Canaanites would dwell in that land.
We are here told upon what terms the rest of the tribes stood with the Canaanites that remained. I. Benjamin neglected to drive the Jebusites out of that part of the city of Jerusalem which fell to their lot, Jdg 1:21. Judah had set them a good example, and gained them great advantages by what they did (Jdg 1:9), but they did not follow the blow for want of resolution.
Commenting on Judges 1:21-36
Neither did Manasseh,.... One of the sons of Joseph before mentioned; and it respects that half tribe of Manasseh, which had its portion on this side Jordan in the land of Canaan: these did not drive out the inhabitants of Bethshean and her towns, nor Taanach and her towns, nor the inhabitants of Dor and her towns, nor the inhabitants of Ibleam and her towns...
The same course of subjugation was carried on in the other tribes to a partial extent, and with varying success. Many of the natives, no doubt, during the progress of this exterminating war, saved themselves by flight and became, it is thought, the first colonists in Greece, Italy, and other countries. But a large portion made a stout resistance and retained possession of their old abodes in Canaan.
