'Nations' in the Bible

And 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 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.
