And Zorah,.... The same with Zoreah, Joshua 15:33,

and Aijalon; there was a city of the tribe of Dan of this name, in the valley of which the moon stood still in the times of Joshua, Joshua 10:12, but whether the same with this, and now belonging to Judah, or another of the same name, is not certain:

and Hebron; a city in the mountainous part of Judah, and a city of refuge, about twenty miles from Jerusalem, Joshua 15:54,

which are in Judah and in Benjamin fenced cities; as they were now made by Rehoboam.

Zorah, Samson's birthplace, is represented by the ruin Sura, at the south-west end of the ridge, which encloses the Wady es Surar on the north; see on Joshua 15:33. To the north of that again lay Ajalon, now the village Jlo, on the verge of the plain Merj ibn Omeir, four leagues to the west of Gibeon; see on Joshua 10:12 and Joshua 19:42. Finally, Hebron, the ancient city of the patriarchs, now called el Khalil (The friend of God, i.e., Abraham); see on Genesis 23:2. All these fenced cities lay in the tribal domain of Judah, with the exception of Zorah and Ajalon, which were assigned to the tribe of Dan (Joshua 19:41.). These two were probably afterwards, in the time of the judges, when a part of the Danites emigrated from Zorah and Eshtaol to the north of Palestine (Judges 18:1), taken possession of by Benjamites, and were afterwards reckoned to the land of Benjamin, and are here named as cities which Rehoboam fortified in Benjamin. If we glance for a moment at the geographical position of the whole fifteen cities, we see that they lay partly to the south of Jerusalem, on the road which went by Hebron to Beersheba and Egypt, partly on the western slopes of the hill country of Judah, on the road by Beit-Jibrin to Gaza, while only a few lay to the north of this road towards the Philistine plain, and there were none to the north to defend the kingdom against invasions from that side. "Rehoboam seems, therefore, to have had much more apprehension of an attack from the south and west, i.e., from the Egyptians, than of a war with the northern kingdom" (Berth.). Hence we may conclude that Rehoboam fortified these cities only after the inroad of the Egyptian king Shishak.

And Zorah, and Aijalon, and Hebron, which are in Judah and in Benjamin fenced cities.

11:1-12 A few good words might have prevented the rebellion of Rehoboam's subjects; but all the force of his kingdom cannot bring them back. And it is in vain to contend with the purpose of God, when it is made known to us. Even those who are destitute of true faith, will at times pay some regard to the word of God, and be kept by it from wrong actions, to which they are prone by nature.
