Gentiles
Gentiles, in the Old Testament, translates a Hebrew word, meaning "foreigners" as opposed to Israelites. In the New Testament it is used to translate two Greek words, ethne, "nations," corresponding to the Hebrew word mentioned above, and Hellenes, literally "Greeks" (as in Romans ii. 9, 10, etc.). Most of the foreigners with whom the apostles came in contact spoke Greek.
