Matthew Poole and continuators on Joshua 19:47

47 And the coast of the children of Dan went out too little for them , therefore the children of Dan went up to 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.

Heb. Went out from them, to wit, out of their hands or Possession; for so this Hebrew Word is used concerning those Lands, which in the year of Jubilee are said to go out, Levit. 25. 28, 30, 31, 33. i. e. out of the hands of the present Possessor, to the first and ancient Owner. And so peradventure this may signifie, that many of the Danites were forced by their powerful Neighbours the Philistins to relinquish their Coast, and their allotted Habitations: which put them upon the following course.

This was done after Ioshuah's death, as appears from Iudg. 18. and seems to be here inserted, partly that all the Chief Places where the Danites (dwelt) though far distant, might be mentioned together; and partly, 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 and terrified 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, or at least, was not in the Possession of any other Tribe. See more on Iudg. 18.
