Commentators explain that Kiriath-jearim, where the Danites camped, was a historically significant site in Judah. It was known as the 'city of forests' and, most notably, was the place where the Ark of the Covenant rested for twenty years after being returned by the Philistines. This detail adds a layer of irony, as the Danites were passing through a place of past holiness on a mission of theft and idolatry.
