Priesthood (ancient Israel)
The priesthood of ancient Israel was the class of male individuals, who, according to the Hebrew Bible, were patrilineal descendants from Aaron (the elder brother of Moses) and they were assisted by the tribe of Levi, who served in the Tabernacle, Solomon's Temple and Second Temple until the destruction of Jerusalem in 70 CE. Their temple role included animal sacrifice. The priests (Hebrew kohanim) are viewed as continuing in the Kohen families of rabbinical Judaism. The Levites were not technically priests, they were the priests assistants and are viewed as continuing in the Levite families of rabbinical Judaism.
