'Macedonians' in the Bible

because I know your readiness [to help], [concerning] which I keep on boasting to the Macedonians about you, that Achaia has been ready [to help] since last year, and your zeal has stirred up the majority [of them].

lest somehow if Macedonians should come with me and find you unprepared, we--{not to speak of you}--would be humiliated in connection with this project.
