1 Samuel 27:6-8

King James Version

⁶ Then Achish gave him Ziklag that day: wherefore Ziklag pertaineth unto the kings of Judah unto this day.

⁷ And the time that David dwelt in the country of the Philistines was a full year and four months.

⁸ And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites: for those nations were of old the inhabitants of the land, as thou goest to Shur, even unto the land of Egypt.
