'Nations' in the Bible

The vision of Obadiah. This is what the Lord has said about Edom: We have had word from the Lord, and a representative has been sent among the nations, saying, Up! and let us make war against her.

See, I have made you small among the nations: you are much looked down on.

For the day of the Lord is coming quickly on all nations: as you have done it will be done to you; the reward of your acts will come on your head.

For as you have been drinking on my holy mountain, so will all the nations go on drinking without end; they will go on drinking and the wine will go down their throats, and they will be as if they had never been.
