1 Samuel 27:6-9
English Standard Version
Chapter 27
6So that day Achish gave him Ziklag. Therefore Ziklag has belonged to the kings of Judah to this day. 7And the number of the days that David lived in the country of the Philistines was a year and four months.
8Now David and his men went up and made raids against the Geshurites, the Girzites, and the Amalekites, for these were the inhabitants of the land from of old, as far as Shur, to the land of Egypt.
9And David would strike the land and would leave neither man nor woman alive, but would take away the sheep, the oxen, the donkeys, the camels, and the garments, and come back to Achish.
