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.
David ... went up, and invaded the Geshurites (see Joshua 13:2 ), and the Gezerites - or the Gerizi (Gesenius: Joshua 12:12), some Arab horde which had once encamped there.
And the Amalekites. Part of the district occupied by them lay on the south of the land of Israel (Judges 5:14; Judges 12:15); but after the overthrow of their national strength by Saul (1 Samuel 15:1-35) they dispersed and became a horde of desert marauders.
As thou goest to Shur, [Septuagint, Gelampsour] - (see the note at Genesis 13:10; Genesis 16:7; Genesis 20:1; Genesis 25:18.)
