According to Abrahamic religions, Aaron ( AIR-ən or ARR-ən) was a Jewish prophet, a high priest, and the elder brother of Moses. Information about Aaron comes exclusively from religious texts, such as the Hebrew Bible, the New Testament (Luke, Acts, and Hebrews), and the Quran. The Hebrew Bible relates that, unlike Moses, who grew up in the Egyptian royal court, Aaron and his elder sister Miriam remained with their kinsmen in the northeastern region of the Nile Delta.
