Young's Literal Translation

⁶ And Achish giveth to him in that day Ziklag, therefore hath Ziklag been to the kings of Judah till this day.

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,
