6 Then Achish gave him Ziklag that day: why Ziklag pertains to the kings of Judah to this day.

Ziklag - This was properly one of the cities of Simeon within the tribe of Judah (marginal references), but it had been taken possession of by the Philistines. The exact situation of it is uncertain.
Unto this day - This phrase, coupled with the title the kings of Judah, implies that this was written after the revolt of Jeroboam, and before the Babylonian captivity.
Achish gave him Ziklag - Ziklag was at first given to the tribe of Judah, but afterwards it was ceded to that of Simeon, Joshua 15:31; Joshua 19:5. The Philistines had, however, made themselves masters of it, and held it to the time here mentioned; it then fell into the tribe of Judah again, and continued to be the property of the kings of Judah. This verse is a proof that this book was written long after the days of Samuel, and that it was formed by a later hand, out of materials which had been collected by a contemporary author. See the preface.
Then Achish gave him Ziklag that day,.... A city which in the division of the land was given to the tribe of Judah, and after that to the tribe of Simeon, Joshua 15:31; though it seems not to have been possessed by either of them, at least not long, but soon came into the hands of the Philistines, who kept it till this time, and now it returned to its right owners; according to Bunting (g) it was twelve miles from Gath:
wherefore Ziklag pertaineth unto the kings of Judah unto this day; not to the tribe of Judah, though it originally belonged to it, but to the kings of it, it, being granted to David, who quickly after this became king of Judah; and this was annexed to the crown lands, and ever after enjoyed by the kings, of the house of Judah; for this was not given for a temporary habitation, but for perpetual possession. This clause seems to be added by the continuator of this history, after the death of Samuel; who might be Gad or Nathan; some say Ezra, and Abarbinel that Jeremiah was the writer of it.
(g) Travels, &c. p. 136.
Ziklag--Though originally assigned to Judah (Joshua 15:31), and subsequently to Simeon (Joshua 19:5), this town had never been possessed by the Israelites. It belonged to the Philistines, who gave it to David.
Gave Ziklag - Not only to inhabit, but to possess it as his own. Which he did, to lay the greater obligations upon David, whom he knew so able to serve him. It was given to the tribe of Judah before, Joshua 15:31, but the Philistines kept the possession of it 'till this time. And being given by them to David, it now belonged not to the tribe of Judah; but to the king of Judah, David and his heirs forever. To this day - This, and some such clauses seem to have been added, after the main substance of the several books was written.
