Hebrew was Gods choice for the OT because the Jews were to be the oracles of the OT, and the language of record to Gods people.
Greek and Latin existed at the same time in the new church, God chose greek
Wat do you know about the spread of Latin over the eastern Med? One criticism of Gibson’s movie was that the soldiers should have been speaking Greek.
Where do you get that information?
At the time in the Holy Land, Aramaic was the common language of the people, Hebrew was the language of the priesthood and ancient documents, Latin was the language of the conquerors, but Greek was the Lingua Franca of the entire world and would remain that way for the next 400 years, when Latin succeeded it; French replaced Latin in the 1600s and English replaced French in the 1800s.
Of course Greek was chosen since it was the language that most people on earth knew, at least as a second language.
