Commentary on Exodus 29

Exodus 29 details the elaborate, seven-day consecration ceremony for Aaron and his sons to serve as priests, along with the dedication of the Tabernacle altar. This chapter outlines specific sacrifices—a bull for a sin offering, and two rams for a burnt offering and an ordination offering—along with their precise rituals. The meticulous instructions underscore the holiness required for those approaching God and the sacredness of the space where His presence would dwell, establishing the foundational practices for Israel's worship.

Historical context

The book of Exodus records the liberation of Israel from Egyptian bondage and their journey to Mount Sinai, where God establishes a covenant with them. Following the giving of the Ten Commandments and other laws, a significant portion of Exodus (chapters 25-31 and 35-40) is dedicated to the instructions for building the Tabernacle and establishing its worship. Exodus 29 falls within this section, specifically detailing the ordination of the priesthood.

The historical context is critical: Israel, recently freed from slavery, is now being constituted as a holy nation, a “kingdom of priests and a holy nation” (Exod 19:6). The elaborate rituals for the priesthood and the Tabernacle were not merely ceremonial; they were pedagogical, teaching Israel about God's holiness, the seriousness of sin, and the necessity of mediation to approach a holy God. The instructions were given directly by God to Moses on Mount Sinai, emphasizing their divine origin and authority.

Verse by verse

• 1:

  This verse introduces the purpose of the chapter: to consecrate Aaron and his sons as priests. The term “consecrate” (Hebrew: qadash, קדש) means to set apart or make holy. This was not a self-appointed role but a divine appointment, requiring specific rituals to prepare them for their sacred duties.

• 4:

  Aaron and his sons were to be brought to the entrance of the Tent of Meeting and washed with water. This washing symbolized purification, a necessary step before entering God's presence or performing sacred service. It prefigures the spiritual cleansing required for all who would draw near to God.

• 7:

  Moses was to anoint Aaron with oil, signifying the Holy Spirit's empowerment for service. This anointing set him apart as the High Priest, a unique role of mediation between God and Israel. This act visually represented God's chosen one being filled and equipped for His divine calling.

• 10:

  The first sacrifice, a bull for a sin offering, required Aaron and his sons to lay their hands on its head. This act transferred their sin and guilt onto the animal, which would then bear the penalty. It underscored the reality of human sin and the need for atonement before God.

• 18:

  The ram for the burnt offering was entirely consumed on the altar, a “pleasing aroma” to the Lord. This offering symbolized complete dedication and surrender to God, acknowledging His sovereignty and seeking His favor. The smoke ascending to heaven represented the offering's acceptance.

• 20:

  Blood from the ram of ordination was applied to the right earlobe, thumb, and big toe of Aaron and his sons. This specific application symbolized the consecration of their hearing (to obey God's word), their hands (to perform God's work), and their feet (to walk in God's ways). It marked them as wholly dedicated to God's service.

• 24:

  The “wave offering” involved Aaron waving specific portions of the sacrifice before the Lord. This act symbolized presenting the offering to God and receiving it back from Him, signifying His acceptance and the priests' right to partake. It was a visual demonstration of the covenant relationship.

• 29:

  The garments of the High Priest were to be passed down to his successors. This ensured continuity in the priesthood and symbolized the ongoing nature of the covenant and the sacred office. The garments themselves were not just clothing but symbols of authority and holiness.

• 35:

  The entire ordination ceremony was to last seven days. This extended period emphasized the thoroughness and solemnity of the consecration. The number seven often signifies completeness and perfection in biblical symbolism, highlighting the divine establishment of the priesthood.

• 38:

  Beyond the ordination, daily offerings of two lambs were commanded for the altar. This established a perpetual rhythm of worship and atonement, reminding Israel of God's constant presence and their ongoing need for reconciliation. It maintained the holiness of the Tabernacle.

• 45:

  God promises, “I will live among the people of Israel and be their God.” This verse reveals the ultimate purpose of the Tabernacle and the priesthood: to facilitate God's dwelling among His people. All the rituals pointed to the desire for intimate communion between God and humanity.

Application

The detailed rituals in Exodus 29, while seemingly distant, offer profound insights for our faith today. They remind us that approaching a holy God is a serious matter, requiring purification and mediation. The elaborate sacrifices, particularly the sin offering and burnt offering, powerfully illustrate the cost of sin and the necessity of a perfect sacrifice for atonement.

For believers in Christ, these Old Testament rituals find their ultimate fulfillment in Jesus. He is our High Priest, consecrated not by bulls and rams, but by His own perfect life and sacrifice (Heb 7:27). His blood cleanses us once for all, making us holy and enabling us to draw near to God with confidence (Heb 10:19-22). We are now a “royal priesthood” (1 Pet 2:9), called to offer spiritual sacrifices of praise and service, empowered by the Holy Spirit. This chapter encourages us to live lives set apart for God, understanding the immense privilege and responsibility of our access to Him through Christ.
