'Nations' in the Bible

and they said unto him, Behold, thou art old, and thy sons walk not in thy ways: now make us a king to judge us like all the nations.

that we also may be like all the nations, and that our king may judge us, and go out before us, and fight our battles.

And David and his men went up, and made a raid upon the Geshurites, and the Girzites, and the Amalekites; for those nations were the inhabitants of the land, who were of old, as thou goest to Shur, even unto the land of Egypt.
