Zebulun failed to drive out the inhabitants of Kitron and Nahalol; so the Canaanites lived among them and served as forced laborers.
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 Zebulun drive out the inhabitants of Kitron, nor the inhabitants of Nahalol,.... The first of these seems to be the same with Kattah or Kartah, and the latter with Nahalal, both cities given to the Levites, Jos 19:15; which perhaps was the reason of their sloth in driving them out; though it aggravated their sin not to take care to rid those cities...
Jdg 1:30 Zebulun did not root out the Canaanites in Kitron and Nahalol.
