Albert Barnes Commentary 2 Samuel 24:7

"and came to the stronghold of Tyre, and to all the cities of the Hivites, and of the Canaanites; and they went out to the south of Judah, at Beer-sheba." — 2 Samuel 24:7 (ASV)

The strong hold of Tyre—"The fenced city," as it is generally rendered throughout the historical books.

The cities of the Hivites—Gibeon, Chephirah, Beeroth, and Kirjath-jearim, and perhaps Shechem, besides those at the foot of Hermon and Lebanon, of which we do not know the names. This continuance of distinct communities of Hivites as late as the end of David’s reign is remarkable.
