1 Samuel 27:6

Then Achish gave him Ziklag that day: wherefore Ziklag pertaineth unto the kings of Judah unto this day.

Ziklag. Though originally assigned to Judah (Joshua 15:31), and subsequently to Simeon (Joshua 19:5: cf. 1 Chronicles 4:30), this town had never been possessed by the Israelites. It belonged to the Philistines, who gave it to David. It remained ever after a private possession of the kings of Judah. Ziklag was a border fortress. 'From its neighbourhood (Joshua 19:5) to Beth-marcaboth (the house of chariots) and Hazar-susah (the village of horses), it appears to have been a kind of fortress for protection from the Bedouin marauders of the caravans, such as Nukhl and Akabah, on the Haj route at the present day' (Drew's 'Scripture Lands,' p. 124).
