'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 was teaching, saying to them, 'Hath it not been written -- My house a house of prayer shall be called for all the nations, and ye did make it a den of robbers?'

and to all the nations it behoveth first that the good news be proclaimed.
