John Wesley on Joshua 19:47

Went up to fight - This was done after Joshua's death, and seems to be here inserted, that all the chief places where the Danites dwelt, tho' far distant, might be mentioned together; and to give an account of this strange accident, why they removed from their appointed portion to so remote a place; which may be this, that being much molested by their bad neighbours, they thought fit to go to some place remote from them, which also they were in a manner constrained to do, because otherwise they must have taken some part of the portions of other tribes, whereas now going to the very utmost northern point of the land, they took that which did not belong to any other tribe.
