1 Samuel 27:8-10

27:8 Then David and his men went up and raided the Geshurites, the Girzites, and the Amalekites. (They had been living in that land for a long time, from the approach to Shur as far as the land of Egypt.) 27:9 When David would attack a district, he would leave neither man nor woman alive. He would take sheep, cattle, donkeys, camels, and clothing and would then go back to Achish. 27:10 When Achish would ask, “Where did you raid today?” David would say, “The Negev of Judah” or “The Negev of Jeharmeel” or “The Negev of the Kenites.”
