'Nations' in the Bible

and they said to him, "Behold, you are old, and your sons don't walk in your 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."

David and his men went up, and made a raid on the Geshurites, and the Girzites, and the Amalekites; for those [nations] were the inhabitants of the land, who were of old, as you go to Shur, even to the land of Egypt.
