Easton's Bible Dictionary (1897)/Gentiles
Gentiles: (Heb., usually in plural, goyim), meaning in general all nations except the Jews. In course of time, as the Jews began more and more to pride themselves on their peculiar privileges, it acquired unpleasant associations, and was used as a term of contempt.
In the New Testament the Greek word Hellenes, meaning literally Greek (as in Acts 16:1,3; 18:17; Romans 1:14), generally denotes any non-Jewish nation.
