 The Hebrew sound had no direct equivalent in Greek, when Jewish scriptures were translated by Greek-speaking Jews in Alexandria around 200 BCE to form the septuagint, so these translators used a pair of Greek alpha letters to approximate the same sound, "Ααρών".This was translated again by St. Jerome from the Greek to the Latin Vulgate as "Aaron" in the fourth century CE.It is thought that the Greeks and Romans would pronounce Aaron similarly to the Hebrew, as the Catholic Latin pronunciation is still defined this way.
