And the coast of the children of Dan went out too little for them: therefore the children of Dan went up to {l} fight against Leshem, and took it, and smote it with the edge of the sword, and possessed it, and dwelt therein, and called Leshem, Dan, after the name of Dan their father.

(l) According as Jacob had prophesied in Ge 49:17.

Wesley's Notes

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.

Jamieson-Fausset-Brown Bible Commentary

47. the children of Dan went up to fight against Leshem-The Danites, finding their inheritance too small, decided to enlarge its boundaries by the sword; and, having conquered Leshem (Laish), they planted a colony there, calling the new settlement by the name of Dan (see on [200]Jud 18:7).

Matthew Henry's Concise Commentary

19:17-51 Joshua waited till all the tribes were settled, before he asked any provision for himself. He was content to be unfixed, till he saw them all placed, and herein is an example to all in public places, to prefer the common welfare before private advantage. Those who labour most to do good to others, seek an inheritance in the Canaan above: but it will be soon enough to enter thereon, when they have done all the service to their brethren of which they are capable. Nor can any thing more effectually assure them of their title to it, than endeavouring to bring others to desire, to seek, and to obtain it. Our Lord Jesus came and dwelt on earth, not in pomp but poverty, providing rest for man, yet himself not having where to lay his head; for Christ pleased not himself. Nor would he enter upon his inheritance, till by his obedience to death he secured the eternal inheritance for all his people; nor will he account his own glory completed, till every ransomed sinner is put in possession of his heavenly rest.

Matthew Henry's Whole Bible Commentary

Verses 40-48

Dan, though commander of one of the four squadrons of the camp of Israel, in the wilderness, that which brought up the rear, yet was last provided for in Canaan, and his lot fell in the southern part of Canaan, between Judah on the east and the land of the Philistines on the west, Ephraim on the north and Simeon on the south. Providence ordered this numerous and powerful tribe into a post of danger, as best able to deal with those vexatious neighbours the Philistines, and so it was found in Samson. Here is an account, 1. Of what fell to this tribe by lot, Zorah, and Eshtaol, and the camp of Dan thereabouts, of which we read in the story of Samson. And near there was the valley of Eshcol, whence the spies brought the famous bunch of grapes. Japho, or Joppa was in this lot. 2. Of what they got by their own industry and valour, which is mentioned here (v. 47), but related at large, Jdg. 18:7, etc.
