Aaron (Hebrew: אַהֲרֹן, Modern: Ahron, Tiberian: ʼAhărôn) is a significant figure in the Hebrew Bible and the Quran, serving as the older brother of Moses and a prophet. In Jewish tradition, Aaron is known as Aharon HaKohen (Aaron the Priest), as he was the first High Priest of the Israelites. The name Aaron is of Hebrew origin and is often translated to mean "mountain of strength" or "exalted" or "enlightened." In Arabic, the name is transliterated as Hārūn (هارون). In the biblical narrative, Aaron plays a crucial role in the events of the Exodus, serving as Moses' spokesman to the Pharaoh and later as the first High Priest of the Israelites. Aaron's descendants, the Aaronites, were the only ones entitled to the priesthood in Judaism. The name Aaron has been widely used in various cultures and languages, reflecting its historical and religious significance.
