'Nations' in the Bible

The nations will hear and tremble; anguish will seize the inhabitants of Philistia.

And now, if you will diligently listen to me and keep my covenant, then you will be my special possession out of all the nations, for all the earth is mine,

For I will drive out the nations before you and enlarge your borders; no one will covet your land when you go up to appear before the Lord your God three times in the year.
