Unto the reign of David - It is not quite clear why this clause is added. Perhaps the writer is quoting from a document belonging to David's reign. Or, he may mean that some of the cities, as Ziklag 1-Samuel 27:6, were lost to Simeon about David's time.

These were their cities unto the reign of David - It appears that David took some of the cities of the Simeonites, and added them to Judah; Ziklag for instance, 1-Samuel 27:6.
As the tribe of Simeon had withdrawn their allegiance from the house of David, the kings of Judah extended their domination as far as possible into the territories of that tribe, so that they were obliged to seek pasture for their flocks at Gedor, and in the mountains of Seir, as we find 1-Chronicles 4:39-42.

And at Bethmarcaboth, and Hazarsusim, and at Bethbirei, and at Shaaraim. These [were] their cities unto the reign of (k) David.
(k) Then David restored them to the tribe of Judah.

These were their cities unto the reign of David--In consequence of the sloth or cowardice of the Simeonites, some of the cities within their allotted territory were only nominally theirs. They were never taken from the Philistines until David's time, when, the Simeonites having forfeited all claim to them, he assigned them to his own tribe of Judah (1-Samuel 27:6).

Their cities - Several of these cities though given to Simeon by Joshua, yet through the sloth or cowardice of that tribe, were not taken from the Philistines, until David's time, who took some of them; and, the Simeonites having justly forfeited their right to them by their neglect, gave them to his own tribe. For it is evident concerning Ziklag, one of them, that it was in the Philistines hands in David's time, and by them given to him, and by him annexed to the tribe of Judah, 1-Samuel 27:6.
