This is the inheritance of the tribe of the children of Dan according to their families, these cities with their villages.

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.
