'Nations' in the Bible

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

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

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

And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
