1 Samuel 27:8; 1 Samuel 27:9

8 Now David and his men went up and raided the Geshurites and the Girzites and the Amalekites; for they were the inhabitants of the land from ancient times, as you come to Shur even as far as the land of Egypt.

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