'Nations' in the Bible

-- 'Lo, we go up to Jerusalem, and the Son of Man shall be delivered to the chief priests, and to the scribes, and they shall condemn him to death, and shall deliver him to the nations,

but Jesus having called them near, saith to them, 'Ye have known that they who are considered to rule the nations do exercise lordship over them, and their great ones do exercise authority upon them;

And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves.

And the gospel must first be published among all nations.
