the Geshurites, the Girzites, and the Amalekites: These groups lived on the edges of the southern desert and caused problems for both the Philistines and Israelites. (For more on the Amalekites, see 1 Samuel 14:48; 15; for more on the Geshurites, see Joshua 13:2, 13; 2 Samuel 3:3.)
Shur was somewhere east of Egypt (1 Samuel 15:7; Genesis 16:7; 20:1; 25:18).
