Joshua returned - The words mark a change in the direction of the march. Joshua from Hebron turned to the southwest, and attacked Debir or Kirjath-sepher and its dependencies Joshua 15:15.
And Joshua returned, and all Israel with him, to Debir,.... A city, according to Kimchi, which he passed by when he went to Hebron, and did not fight against it; but, when he had taken Hebron, returned and took it; and which Bunting (h) says was but a mile from it, and twenty two miles from Jerusalem, towards the south; it is the same with Kirjathsepher and Kirjathsannah, Joshua 15:15; the city of a book or books; and the Rabbins say (i), that with the Persians Debir signifies the same, and had its name from a library which was here kept, or from the archives in which the most memorable things since the flood were recorded; or from the making of paper or parchment, or whatsoever was made use of for writing, and of which volumes of books were made:
and fought against it; it refusing to submit to him upon his summons.
(h) Travels of the Patriarchs, &c. p. 96. (i) T. Bab. Avodah Zarah, fol. 24. 2.
Joshua returned - He is said to return thither, not as if he had been there before, but because having gone as far westward and southward as he thought fit, even as far as Gaza, Joshua 10:41, he now returned towards Gilgal, which lay north - ward and eastward from him, and in his return fell upon Debir.
