In the Hebrew Bible and the Quran, Aaron was the older brother of Moses, , a prophet of God. Unlike Moses who grew up in the Egyptian royal court, Aaron and his sister Miriam remained with their kinsmen in the eastern border-land of Egypt . When Moses first confronted the Egyptian king about the Israelites, Aaron served as his brother's spokesman to Pharaoh. Part of the Law that Moses received from God at Sinai granted Aaron the priesthood for himself and his male descendants, and he became the first High Priest of the Israelites. Various dates for his life have been proposed, ranging from approximately 1600 to 1200 BC. Aaron died before the Israelites crossed the Jordan river and he was buried on Mount Hor Aaron is also mentioned in the New Testament of the Bible.
