Aaron Priesthood

The Aaronic priesthood is the hereditary sanctuary office entrusted to Aaron and his sons: they alone serve at the altar and within the veil, while the Levites assist with the Tent of Meeting but may not approach its sacred furnishings or altar. Its duties, boundaries, and provision together define a system intended to protect the sanctuary and prevent further judgment upon the people.

Office and Boundaries

The priesthood is assigned to Aaron and his sons as a service and a gift. They bear responsibility for the sanctuary and for their priestly office, and they must keep the charge of the holy things and the altar. A person outside the priestly office who approaches is subject to death; the boundary is stated as a safeguard against wrath falling again upon the Israelites.

The Levites are brought near to assist the priests and serve the Tent of Meeting. They keep its charge, but they must not approach the holy furnishings or altar. The division of labor is explicit: the Levites perform sanctuary service, while Aaron and his sons retain the priestly duties associated with the altar and the space within the veil.

Duties and Material Support

The priestly share includes offerings reserved from the fire: meal offerings, sin offerings, and guilt offerings, which are most holy and are to be eaten by the males of Aaron’s household in a most holy place. Wave offerings belong to Aaron’s sons and daughters as a continuing due, and members of the household may eat them when clean. The best oil, wine, and grain, together with the first ripe produce brought to the LORD, are also assigned to the priestly household.

The firstborn provision distinguishes human beings and unclean animals from sacrificial livestock. Firstborn males offered to the LORD belong to the priesthood, but a human firstborn must be redeemed, as must the firstborn of an unclean animal; the redemption payment is five sanctuary shekels from the age of one month. The firstborn of an ox, sheep, or goat is not redeemed: its blood is applied to the altar and its fat is offered, while its flesh belongs to the priests.

The priestly portions are described as an enduring covenant of salt. In contrast to the other Israelites, Aaron has no territorial inheritance: the LORD is declared to be his portion and inheritance. The Levites likewise have no land inheritance, receiving Israel’s tithe in return for their service at the Tent of Meeting.

The Tithe and Its Redistribution

The Levites must set aside a tenth of the tithe they receive and present it as a gift to the LORD. Their contribution is reckoned as though it came from the threshing floor or winepress, and they must give the best portion to Aaron the priest. After setting it apart, the Levites may consume the remainder with their households wherever they are; it is their reward for service at the Tent of Meeting.

This arrangement links sanctuary service to a defined flow of agricultural resources: the Israelites’ tithe supports the Levites, and the Levites’ tithe supports the priest. The Levites’ lack of landed inheritance is answered by this provision, while the priestly office receives both offerings and the best share of the Levites’ contribution.

Ritual Authority and Institutional Continuity

Priestly authority also appears in the red-heifer purification rite. Eleazar the priest receives the unblemished animal outside the camp, sprinkles its blood seven times toward the front of the Tent of Meeting, and supervises its burning with cedar wood, hyssop, and scarlet material. The ashes are kept in a clean place for the congregation’s purification water. This rite makes the priest an authorized mediator of a procedure that restores people made unclean through contact with the dead.

The priesthood’s standing is set within a broader inheritance order. When the daughters of Zelophehad petition for their father’s estate because he has no son, the LORD establishes a succession rule granting daughters inheritance in that circumstance, followed by other relatives in order. The ruling concerns inheritance rather than priestly appointment, but it clarifies the distinct status of the priestly household: its sanctuary provision and hereditary office are not presented as a territorial allotment.
