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 Beersheba.

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 so late as the end of David's reign is remarkable.
The strong hold of Tyre - This must have been the old city of Tyre, which was built on the main land: the new city was built on a rock in the sea.
And came to the strong hold of Tyre,.... That is, old Tyre, which stood thirty furlongs from new Tyre, the island (y); of which See Gill on Isaiah 23:1; this must be understood of the parts near unto it; for that itself was not within the land of Israel, and so its inhabitants not to be numbered:
and to all the cities of the Hivites, and of the Canaanites: which were possessed by them, and from whence they were not driven out by the Israelites; to all places contiguous to them, Joab and his captains came to take the number of them:
and they went out to the south of Judah: even to Beersheba; passing through the western part of the land, they came to the southern part of it, even as far as Beersheba, which was the extreme part of the land to the south.

Thence southwards to the fortress of Zor, i.e., Tyre (see at Joshua 19:29), and "into all the towns of the Hivites and Canaanites," i.e., the towns in the tribes of Naphtali, Zebulun, and Issachar, or the (subsequent) province of Galilee, in which the Canaanites had not been exterminated by the Israelites, but had only been made tributary.
