'Nations' in the Bible

For all the nations of the world pursue these things, and your Father knows that you need them.

They will fall by the edge of the sword and be led away as captives among all nations. Jerusalem will be trampled down by the Gentiles until the times of the Gentiles are fulfilled.

"And there will be signs in the sun and moon and stars, and on the earth nations will be in distress, anxious over the roaring of the sea and the surging waves.

and repentance for the forgiveness of sins would be proclaimed in his name to all nations, beginning from Jerusalem.
