'Nations' in the Bible

The vision of Obadiah. Thus saith the Lord Jehovah concerning Edom: We have heard tidings from Jehovah, and an ambassador is sent among the nations,'saying , Arise ye, and let us rise up against her in battle.

Behold, I have made thee small among the nations: thou art greatly despised.

For the day of Jehovah is near upon all the nations: as thou hast done, it shall be done unto thee; thy dealing shall return upon thine own head.

For as ye have drunk upon my holy mountain, so shall all the nations drink continually; yea, they shall drink, and swallow down, and shall be as though they had not been.
