There was no deliverer, because it was far from Sidon, and they had no dealings with any man; and it was in the valley that lies by Beth Rehob. They built the city, and lived therein.
Note in Judges 18:27 that the Danites took three things: the "gods" that Micah had made (cf. Judges 18:14), a priest whom they could buy, and a town that its inhabitants could not defend. On these flimsy foundations the Danites built their future in the North.
