1 Samuel 27:8-10

8Then 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.)

9When 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.

10When 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.”
