In the Hebrew Bible and the Qur'an, Aaron ( /ˈærən/ or /ˈɛərən/;Hebrew: אַהֲרֹן‎ Ahărōn, Arabic: هارون‎ Hārūn, Greek (Septuagint): Ααρών ), who is often called "'Aaron the Priest"' (אֵהֲרֹן הֵכֹּהֵן) and once Aaron the Levite (אַהֲרֹן הַלֵּוִי) (Exodus 4:14), was the older brother of Moses, (Exodus 6:16-20, 7:7; Qur'an 28:34) and a prophet of God. He represented the priestly functions of his tribe, becoming the first High Priest of the Israelites. While Moses was receiving his education at the Egyptian royal court, and during his exile among the Midianites, Aaron and his sister Miriam remained with their kinsmen in the eastern border-land of Egypt (Goshen). There, Aaron gained a name for eloquent and persuasive speech, so that when the time came for the demand upon the Pharaoh to release Israel from captivity, Aaron became his brother’s nabi, or spokesman, to his own people (Exodus 7:1) and, after their unwillingness to hear, to the Pharaoh himself (Exodus 7:9). Various dates for his life have been proposed, ranging from approximately 1600 to 1200 BC.

Aaron Clark (October 16, 1787 – August 2, 1861) was an American politician who became the second popularly elected Mayor of New York, serving two one-year terms from 1837 to 1839. He was a member of the Whig Party, the only member of his party to ever serve as mayor of New York.

Clark was born in Worthington, Massachusetts. He grew up in Vermont, attended Union College in Schenectady, New York, and fought in the War of 1812.

After the war, Clark moved to Albany, New York, and was Clerk of the New York State Assembly from 1814 to 1820. Afterwards he removed to New York City where he worked in banking, ran a lottery, and became involved in local politics. He served as alderman, a powerful position in the charged political climate of the city. He was elected mayor in 1837 and 1838 for one year terms, and was defeated in 1839. He thus became the only Whig to be elected mayor of the strongly Democratic New York.

The main event of that year was the financial Panic of 1837, in which the economy collapsed following several years of boom. New York real estate values plummeted. Many were unemployed, some were homeless. There was widespread dissatisfaction among the working and middle class residents.
