1 Samuel 27:7-9

Young's Literal Translation

⁷ And the number of the days which David hath dwelt in the field of the Philistines [is] days and four months;

⁸ and David goeth up and his men, and they push unto the Geshurite, and the Gerizite, and the Amalekite, (for they are inhabitants of the land from of old), as thou comest in to Shur and unto the land of Egypt,

⁹ and David hath smitten the land, and doth not keep alive man and woman, and hath taken sheep, and oxen, and asses, and camels, and garments, and turneth back, and cometh in unto Achish.
