Leviticus 4

Overview.
This chapter details the laws for sin offerings when different individuals or groups—whether the anointed priest, the whole congregation, a ruler, or a common person—sin unintentionally against God’s commandments. It emphasizes the need for atonement through sacrificial blood and proper ritual, showing how guilt affects both individuals and the community, and how forgiveness is mediated through the priest according to each person’s role and responsibility.

Flow.

• Begins with the sin of the anointed priest, requiring a bull as a sin offering and full ritual at the Tent of Meeting, due to the seriousness of his role.
• Moves to the case of the whole congregation sinning unknowingly, treated with similar gravity as the priest’s sin, requiring a bull and identical rites.
• Addresses a ruler who sins, requiring a male goat and a simplified ritual compared to the bull offerings.
• Concludes with the common person, who may bring either a female goat or lamb, with rites adjusted by status and means, yet still effecting atonement through the priest.

Connections.
Following chapter 3, which describes the peace offering as an expression of fellowship with God, chapter 4 shifts focus to the sin offering, addressing broken fellowship through unintentional violations. It prepares the way for chapter 5, which continues the laws of atonement by expanding to sins of omission and impurity, showing that both actions and failures to act require sacrifice. The progression underscores that all levels of society—leaders and laypeople alike—are accountable before God and in need of expiation, a theme that chapter 5 further develops by addressing more subtle forms of guilt.

What it teaches.
Sin, even when unintentional, creates liability before God and defiles the community, requiring purification through prescribed sacrifice (WCF 19.6; HC LD 3). The seriousness of the offense is measured not only by the act itself but by the status of the sinner—greater responsibility brings greater ritual obligation, as seen in the use of a bull for the priest and congregation. The repeated rituals of laying on of hands, blood manipulation, and fire signify transfer of guilt, divine satisfaction, and cleansing (WCF 8.5). The sin offering, especially in its varied forms, shows that atonement is both particular and comprehensive, covering every rank in Israel, and that forgiveness is granted only through substitutionary sacrifice mediated by the priesthood (HC LD 16; BC Art. 21). The removal of the carcass outside the camp also points forward to the complete bearing away of sin (Lev 16; Heb 13:11–13).

Apply.
The sacrificial system reveals that even unnoticed sins require atonement, which God provided through costly, divinely appointed means.
