'Gentiles' in the Bible

saying , Behold, we go up to Jerusalem; and the Son of man shall be delivered unto the chief priests and the scribes; and they shall condemn him to death, and shall deliver him unto the Gentiles:

And Jesus called them to him, and saith unto them, Ye know that they who are accounted to rule over the Gentiles lord it over them; and their great ones exercise authority over them.
