1 Samuel 27:8-10

8Now David and his men went up and raided the Geshurites, the Girzites, and the Amalekites [the enemies of Israel that Joshua had failed to annihilate]; for they had inhabited the land from ancient times, as one comes to Shur even as far as the land of Egypt.

9David attacked the land and did not leave a man or a woman alive, but he took the sheep, the cattle, the donkeys, the camels, and the clothing, and returned to Achish.

10When Achish asked, “Where did you raid today?” David replied, “Against the Negev (the South country) of Judah, and against the Negev of the Jerahmeelites, and against the Negev of the Kenites.”
