(Note: In this way we may reconcile in a very simple manner the different accounts concerning Jerusalem in Jos 15:63; Jdg 1:8, Jdg 1:21; Jdg 19:11., 1Sa 17:54, and 2 Sam 5-6, without there being the slightest necessity to restrict the conquest mentioned in this verse to the city that was built round Mount Zion, as Josephus does, to the exclusion of the citadel upon Zion itself; or to follow Bertheau, and refer the account of the Jebusites dwelling by the children of Judah in Jerusalem (Jos 15:63) to a time subsequent to the conquest of the citadel of Zion by David-an interpretation which is neither favoured by the circumstance that the Jebusite Araunah still held some property there in the time of David (2Sa 24:21.), nor by the passage in 1Ki 9:20., according to which the descendants of the Amorites, Hittites, Perizzites, Hivites, and Jebusites who still remained in the land were made into tributary bondmen by Solomon, and set to work upon the buildings that he had in hand.)
Jdg 1:9-15
After the conquest of Jerusalem, the children of Judah (together with the Simeonites, Jdg 1:3) went down to their own possessions, to make war upon the Canaanites in the mountains, the Negeb, and the shephelah (see at Jos 15:48; Jos 21:33), and to exterminate them. They first of all conquered Hebron and Debir upon the mountains (Jdg 1:10-15), as has already been related in Jos 15:14-19 (see the commentary on this passage). The forms עִלִּית and תַּחְתּית (Jdg 1:15), instead of עִלִּיֹּות and תַּחְתִּיֹּות (Jos 15:19), are in the singular, and are construed with the plural form of the feminine גֻּלֹּות, because this is used in the sense of the singular, “a spring†(see Ewald, §318, a.).
