'Nations' in the Bible

Which you have made ready before the face of all nations;

For the nations of the world go in search of all these things: but your Father has knowledge that you have need of them.

And they will be put to death with the sword, and will be taken as prisoners into all the nations; and Jerusalem will be crushed under the feet of the Gentiles, till the times of the Gentiles are complete.

And there will be signs in the sun and moon and stars; and on the earth, fear among the nations and doubt because of the loud noise of the sea and the waves;

And that teaching about a change of heart and forgiveness of sins is to be given to Jerusalem first and to all nations in his name.
