In the Old Testament, the purification or ceremonial washing of priests before their consecration is a significant ritual that underscores the holiness required of those who serve in the presence of God. This practice is rooted in the Mosaic Law and is primarily detailed in the book of Exodus and Leviticus.

Biblical Foundation

The initial instructions for the purification of priests are found in Exodus 29 and Leviticus 8. God commands Moses to consecrate Aaron and his sons as priests, setting them apart for sacred duties. The process of consecration involves several steps, including washing, anointing, and the offering of sacrifices.

Exodus 29:4 states, "Then you shall bring Aaron and his sons to the entrance of the Tent of Meeting and wash them with water." This washing symbolizes the removal of impurity and the preparation for holy service. It is a physical act with deep spiritual significance, representing the need for cleanliness and purity before approaching God.

Symbolism and Significance

The washing of the priests serves as a powerful symbol of purification and sanctification. In the ancient Near Eastern context, water was often associated with cleansing and renewal. For the Israelites, this ritual washing was not merely about physical cleanliness but was a profound act of spiritual preparation.

The act of washing signifies the need for inner purity and the cleansing of sin. It reflects the holiness of God and the requirement for those who minister before Him to be set apart and sanctified. This ritual underscores the gravity of approaching a holy God and the necessity of being cleansed from defilement.

New Testament Correlation

The concept of purification through washing finds its fulfillment in the New Testament through the practice of baptism. While the Old Testament ritual was specific to the consecration of priests, baptism in the New Testament is a broader ordinance for all believers, symbolizing the washing away of sin and the believer's identification with the death, burial, and resurrection of Jesus Christ.

Hebrews 10:22 echoes this theme of purification: "let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and our bodies washed with pure water." This passage highlights the continuity of the purification theme from the Old Covenant to the New Covenant, emphasizing the spiritual cleansing available through Christ.

Theological Implications

The purification of priests before consecration highlights the holiness of God and the necessity for those who serve Him to be pure and set apart. It serves as a reminder of the seriousness of sin and the need for atonement and cleansing. This ritual points forward to the ultimate purification available through Jesus Christ, the Great High Priest, who offers a once-for-all sacrifice for sin and provides believers with the means to approach God with confidence.

In summary, the purifications or baptisms of priests before consecration in the Old Testament are a profound expression of the need for holiness and purity in the service of God. They foreshadow the greater purification accomplished through Christ, who cleanses His people and consecrates them for service in His kingdom.Exodus 29:4
And Aaron and his sons you shall bring to the door of the tabernacle of the congregation, and shall wash them with water.
