Dan Takes Laish and Consecrates a Priest
When the Danite force moved north from Judah through Ephraim on their way to conquer Laish, they moved through the highlands of Ephraim, probably because the lowlands were still occupied by Canaanites. To aid them in their battle, the Danites decided to take the shrine of Micah and the Levite with them, probably in imitation of the Israelite practice of having a priest head their fighting forces (compare Deuteronomy 20). We are told that Laish was "far from the Zidonians, and they had no ties with anyone" (Judges 18:7). Thus, they appear to have lived an isolated life, having neither trading nor diplomatic relations with outsiders. In such a condition, without allies, Laish fell to Dan.
After the conquest of Laish, the men of Dan set up Micah's idolatrous figures and consecrated Jonathan, who may very well have been the grandson of Moses (see earlier highlight on Judges 17, "History Out of Sequence"), as their priest, and his sons as their priesthood. The northern Danites retained this idolatrous worship until the time of the captivity of northern Israel around 722 B.C. Moreover, all Israel knew about it, but did nothing to stop it, as required by the law God had given (see Deuteronomy 13:12).
