As the first high priest, Aaron was consecrated by his brother Moses to serve in the tabernacle under a perpetual statute. His primary responsibilities included:12
- Cultic Leadership: Moses delegated all priestly and cultic authority to Aaron and his sons. This role involved overseeing the religious services and rituals performed within the sanctuary.1
- Day of Atonement: Once a year, on Yom Kippur, Aaron held the unique privilege of entering the Holy of Holies, the most sacred inner sanctum of the tabernacle. During this ritual, he would burn incense and sprinkle the blood of sacrificial animals to expiate his own sins and those of the people of Israel.12
- Hereditary Office: The position was established as a hereditary office for life, with Aaronâs sons designated to inherit the priestly garments and duties after him.12
While Aaron is a central figure in the Exodus narrative, his role as high priest specifically defined the liturgical and sacrificial life of the Hebrew tribes in the wilderness.1
