'Nations' in the Bible

Fearful is Jehovah against them, For He made bare all gods of the land, And bow themselves to Him, each from his place, Do all islanders of the nations.

I have cut off nations, Desolated have been their chief ones, I have laid waste their out-places without any passing by, Destroyed have been their cities, Without man, without inhabitant.

Therefore, wait for Me -- an affirmation of Jehovah, For the day of My rising for prey, For My judgment is to gather nations, To assemble kingdoms, To pour out on them Mine indignation, All the heat of Mine anger, For by the fire of My jealousy consumed is all the earth.
