C. F. Keil and Franz Delitzsch on Judges 18:11-12

Jdg 18:11-12 Removal of Six Hundred Danites to Laish - Robbery of Micah’s Images - Conquest of Laish, and Settlement There. - Jdg 18:11, Jdg 18:12. In consequence of the favourable account of the spies who returned, certain Danites departed from Zorea and Eshtaol, to the number of 600 men, accoutred with weapons of war, with their families and their possessions in cattle and goods (see Jdg 18:21), and encamped by the way at Kirjath-jearim (i.e., Kuriyet Enab; see Jos 9:17), in the tribe territory of Judah, at a place which received the permanent name of Mahaneh Dan (camp of Dan) from that circumstance, and was situated behind, i.e., to the west of, Kirjath-jearim (see at Jdg 13:25). The fact that this locality received a standing name from the circumstance described, compels us to assume that the Danites had encamped there for a considerable time, for reasons which we cannot determine from our want of other information. The emigrants may possibly have first of all assembled here, and prepared and equipped themselves for their further march.
