Leviticus 21: The Holiness of the Priests
Leviticus 21 focuses on the holiness required of the priests in Israel. Since the priests were mediators between God and His people, they were called to a higher standard of purity. Their conduct, family life, and physical condition all mattered because they served in the presence of a holy God. This chapter highlights the necessity of sanctification in worship and points forward to Christ, our perfect High Priest.
Restrictions on Mourning and Defilement (Leviticus 21:1–6)
God commands that priests must not defile themselves by touching a dead body, except in the case of close family members—father, mother, son, daughter, brother, or an unmarried sister. This restriction set them apart from the rest of Israel, who had more leniency in mourning practices.
Additionally, priests were forbidden from shaving their heads in pagan mourning rituals or making cuts on their bodies. Such practices were common among the surrounding nations, but God’s priests were to be distinct. Instead of mourning like the pagans, they were to honor God as the source of life.
Marriage Restrictions for Priests (Leviticus 21:7–9)
Priests were not allowed to marry a prostitute or a divorced woman. Their marriages had to reflect purity and integrity because their role as mediators before God required them to be above reproach.
The daughter of a priest who engaged in sexual immorality was to be put to death because her actions profaned her father’s office. This shows that the priesthood was not merely an individual calling but involved the entire household.
The High Priest’s Greater Restrictions (Leviticus 21:10–15)
The high priest, who had the greatest responsibility in ministering before God, had even stricter requirements. He could not defile himself for any dead person, not even for his own parents. His consecration to God was so absolute that he had to avoid all ceremonial impurity.
Likewise, the high priest could only marry a virgin from among his own people. This restriction was meant to preserve the holiness of the priestly line and prevent corruption. His role foreshadowed Christ, our sinless High Priest, who is set apart from sinners and undefiled.
Physical Perfection Required for Priests (Leviticus 21:16–24)
The final section of the chapter lists physical defects that disqualified a man from serving as a priest. Those with blemishes, such as blindness, lameness, or deformities, were not permitted to offer sacrifices. However, they were still allowed to eat the holy food, meaning they remained part of the priestly family but could not perform priestly duties.
This requirement symbolized the perfection needed to approach God. It also pointed to Christ, the true High Priest, who is without defect or sin. Unlike the Levitical priests, whose imperfections disqualified them from serving, Christ is the flawless Mediator who enters God’s presence on our behalf.
Christ in Leviticus 21
Leviticus 21 ultimately reveals the necessity of holiness in approaching God. The priests, as mediators, had to be set apart in a unique way. Their purity, marriage, and physical condition all symbolized the perfect holiness required to stand before the Lord. However, the priesthood under the Old Covenant was temporary and imperfect.
Christ fulfills the role of the High Priest in a far greater way. Unlike the Levitical priests, He does not need to offer sacrifices for Himself, nor is He restricted by human frailty. He is the sinless, perfect Mediator who brings His people into God’s presence once and for all. In Him, believers become a royal priesthood, called to holiness—not through outward rituals, but through the sanctifying work of the Holy Spirit.
