'Nations' in the Bible

Then David’s fame spread into all the lands; and the Lord caused all nations to fear him.

Declare His glory among the nations,His marvelous works among all peoples.

Let the heavens be glad, and let the earth rejoice;And let them say among the nations, “The Lord reigns.”

Then say, “Save us, O God of our salvation;Gather us together and rescue us from the nations,That we may give thanks to Your holy name,And glory in Your praise.”

And what one nation on the earth is like Your people Israel, whom God went to redeem for Himself as a people, to make a name for Yourself by great and awesome and terrible things, by driving out nations from before Your people, whom You redeemed out of Egypt?

King David also dedicated these to the Lord [setting them apart for sacred use], with the silver and the gold which he brought from all the nations: from Edom, Moab, the Ammonites, the Philistines, and from Amalek.
