'Nations' in the Bible

For all these things do the nations of the world seek after: but your Father knoweth that ye have need of these things.

And they shall fall by the edge of the sword, and shall be led captive into all the nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.

And there shall be signs in sun and moon and stars; and upon the earth distress of nations, in perplexity for the roaring of the sea and the billows;

and that repentance and remission of sins should be preached in his name unto all the nations, beginning from Jerusalem.
