1 Samuel 27:8-10

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. 10When Achish asked, “Where have you made a raid today?” David would say, “Against the Negeb of Judah,” or, “Against the Negeb of the Jerahmeelites,” or, “Against the Negeb of the Kenites.”
