The Roles of the Old Testament Priests: Shadows of Our Great High Priest

The Old Testament priesthood is one of the most beautiful and instructive institutions in all of Scripture. God did not establish it as an afterthought or mere ritual. He designed it with great care as part of the Mosaic covenant to reveal His holiness, provide a way for sinful people to approach Him, and — most importantly — to serve as a living shadow that points forward to the Lord Jesus Christ, our perfect and eternal High Priest.

As those who believe the Bible is the inerrant, inspired Word of God and that the Old Testament is filled with types and shadows of the coming Messiah (Colossians 2:17; Hebrews 10:1), we study these roles with reverence and expectation. Understanding the Old Testament priests helps us appreciate the surpassing glory of Christ and strengthens our faith as we live as a “royal priesthood” under the new covenant (1 Peter 2:9).

 The Divine Institution of the Priesthood

The priesthood began with God’s direct command to Moses. In Exodus 28–29 and Leviticus 8–9, the Lord instructed that Aaron and his sons be set apart as priests. This was not a position any man could claim for himself. God sovereignly chose the tribe of Levi and, within that tribe, the family of Aaron for this holy service.

The consecration ceremony was solemn and lengthy. It involved washing, anointing with oil, the offering of sacrifices, and the application of blood to the priests’ right ear, thumb, and big toe — symbolizing that their hearing, their work, and their walk must all be dedicated to the Lord. This beautiful picture reminds us that true service to God requires total surrender.

The Garments of Glory and Beauty

God commanded that the priests wear special garments “for glory and for beauty” (Exodus 28:2). These were not mere uniforms; they were rich with symbolism.

- The **ephod** and **breastplate** bore the names of the twelve tribes of Israel on the high priest’s shoulders and over his heart. This pictured his role as intercessor — carrying the people before God.

- The **Urim and Thummim** in the breastplate allowed the high priest to seek divine guidance in difficult matters.

- The **golden plate** on the turban read “HOLINESS TO THE LORD,” declaring that the priest represented a holy God.

- The **robe** with bells and pomegranates reminded the people that the priest was alive and serving inside the Holy Place.

These garments teach us that the priest’s work was both representative and intercessory. He stood in the gap between a holy God and a sinful nation.

The Daily and Continual Ministry of the Priests

The ordinary priests had ongoing responsibilities in the Tabernacle (and later the Temple):

- **Offering the daily sacrifices** — Every morning and evening a lamb was offered as a burnt offering (Exodus 29:38-42). This continual sacrifice pointed to the need for ongoing atonement and ultimately to Christ, the Lamb of God who takes away the sin of the world (John 1:29).

- **Burning incense** on the golden altar — This represented the prayers of God’s people ascending before Him (Psalm 141:2; Revelation 8:3-4).

- **Maintaining the golden lampstand** — The priests kept the lamps burning continually, symbolizing the light of God’s presence and truth.

- **The table of showbread** — Twelve loaves were placed before the Lord each week, representing the twelve tribes in fellowship with God.

These duties were never-ending because sin and the need for cleansing never ended under the old covenant.

The Sacrificial System

The heart of the priest’s work was offering the five main offerings described in Leviticus 1–7: the burnt offering, grain offering, peace offering, sin offering, and trespass offering. Each had specific purposes — some for worship and thanksgiving, others specifically for dealing with sin.

On the **Day of Atonement** (Leviticus 16), the high priest alone entered the Most Holy Place once a year with the blood of a bull for himself and a goat for the people. He sprinkled the blood on the mercy seat. This was the most solemn day in Israel’s calendar and the clearest picture of substitutionary atonement in the Old Testament.

Yet even these sacrifices had to be repeated year after year because “it is not possible that the blood of bulls and of goats should take away sins” (Hebrews 10:4).

The Teaching and Mediatorial Role

The priests were also teachers. God commanded:

> “For the priest’s lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the LORD of hosts.” (Malachi 2:7, KJV)

They were to instruct the people in God’s Law, distinguish between holy and unholy, and help the people understand how to walk in obedience (Leviticus 10:10-11; Deuteronomy 33:10).

The high priest also served in a judicial capacity when difficult cases arose, using the Urim and Thummim to discern God’s will.

 Strict Requirements of Holiness

The standards for priests were extremely high (Leviticus 21–22). They had to maintain ritual and moral purity. Any defilement disqualified them from service until they were cleansed. The high priest was under even stricter rules — he could not even mourn the death of close family members in the usual way because he belonged to God in a unique sense.

These rigorous requirements underscored a vital truth: sinful men could never perfectly represent a holy God or fully atone for other sinners. The system was designed to expose this need.

The Limitation and the Shadow

Despite all its beauty and divine origin, the Old Testament priesthood had fatal limitations:

- The priests were sinners who needed sacrifices for themselves.

- The sacrifices had to be repeated constantly.

- The high priest eventually died and had to be replaced.

- Access to God’s presence was severely restricted (only the high priest once a year, and only with blood).

All of this was by God’s design. The entire system was a **shadow** pointing to the coming reality — Jesus Christ.

Fulfilled in Our Great High Priest

The book of Hebrews beautifully explains how Jesus fulfills and surpasses every aspect of the Old Testament priesthood:

- He was appointed by God (Hebrews 5:4-6).

- He is sinless and needed no sacrifice for Himself (Hebrews 4:15; 7:26-27).

- He offered Himself once for all as the perfect sacrifice (Hebrews 9:12; 10:10).

- He lives forever to make intercession for us (Hebrews 7:25).

- He has opened the way into the very presence of God for every believer (Hebrews 10:19-22).

What the old priests could only picture, Christ has accomplished forever.

Application for Believers Today

Because of Christ’s finished work, every true believer is now part of a royal priesthood (1 Peter 2:5, 9; Revelation 1:6). We do not offer animal sacrifices, but we are called to offer:

- The sacrifice of praise (Hebrews 13:15)

- Our bodies as living sacrifices (Romans 12:1)

- Good works and generosity (Hebrews 13:16)

We approach God directly through Jesus, our Great High Priest, with boldness and confidence.

Church leaders today are not atoning priests; they are undershepherds who point people to the one true High Priest. And every Christian is called to live in holiness, intercede for others in prayer, and declare the praises of Him who called us out of darkness into His marvelous light.

Conclusion

The Old Testament priests served faithfully for centuries, but they were always meant to point beyond themselves. Every garment, every sacrifice, every act of intercession, and every requirement of holiness was a divine signpost directing God’s people to the Lord Jesus Christ.

Oh, what mercy and wisdom our God has shown! He gave the shadow so that when the Substance came, we would recognize Him and rejoice.

May this study deepen your love for Christ, strengthen your confidence in His finished work, and stir you to live as a faithful priest in His royal priesthood.

To Jesus Christ, the Great High Priest, be glory and dominion forever and ever. Amen.
