1Sam 15.7 And Saul smote the Amalekites from Havilah until thou comest to Shur, that is over against Egypt.
1Sam 27.8 And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites: for those nations were of old the inhabitants of the land, as thou goest to Shur, even unto the land of Egypt.
