Aaron

Aaron (Hebrew אַהֲרֹן) was the older brother of Moses and the first High Priest of the Israelites. Aaron's children became the Kohanim, the caste of Israelites responsible for offering sacrifices in the Tabernacle and later the Temple. Aaron had four children Eleazar, Itamar, Nadab and Abihu. Nadab and Abihu died after offering incense in a problematic way to God.
