Research Summary
- Meaning: The altar was cleansed and consecrated through seven days of sin offerings and anointing, symbolizing the removal of ceremonial impurity and pointing to Christ.
- Key words: ḥiṭṭē’ (cleanse, un-sin, Piel); mizbēaḥ (altar); qiddēsh (consecrate); kappārōt (atonement).
- Main debate: Whether the altar’s cleansing is purely ceremonial (infection by human sin) or strictly typological (foreshadowing Christ's bearing of sin).

Scholars' Consensus
Commentators agree that Exodus 29:36 prescribes a seven-day ritual in which the altar is cleansed, anointed, and consecrated through a sin offering. The key verb is ḥiṭṭē’ (Piel of ḥāṭā’), meaning “to un-sin” or “purify from sin.” As the Cambridge Bible notes, the Hebrews conceived of sin as capable of infecting even a material object. Gill emphasizes that while the altar was not morally guilty, it required ceremonial expiation because it would bear sin offerings and contact the people’s uncleanness (Leviticus 16:18). Calvin reads the rite typologically: the altar prefigures Christ, who though sinless, became the place of atonement. Gill and Matthew Henry develop this further, seeing the anointing as Christ’s sanctification for His priestly work. The consensus is that the repeated sacrifices highlight the insufficiency of animal offerings and point forward to the final, sufficient sacrifice of Christ.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Ceremonial-cleansing view: Emphasizes the Hebrew concept of sin as a contaminant that infects objects (Cambridge Bible, Gill). The altar is not morally guilty but needs purification from the ritual impurity of human contact and sin offerings.
- Typological view: Reads the altar as a type of Christ, who though sinless, bore the sins of the world and was sanctified for His priestly work (Calvin, Matthew Henry, Wesley).
What is clear: The verse prescribes a seven-day ritual of sin offering, cleansing, and anointing to consecrate the altar for holy worship.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of the altar's uncleanness | All commentators agree that the altar needed ceremonial cleansing due to its contact with a sinful people and sin offerings. | Some (Cambridge Bible, Gill) emphasize a quasi-physical contamination; others (Calvin, Matthew Henry) focus on its typological function to represent Christ's bearing of sin. |
| Meaning of the verb ḥiṭṭē’ | The Piel form of ḥāṭā’ means to purify from sin or to offer a sin offering. | Whether the sense is primarily ‘make a sin offering for’ or ‘un-sin’ (a rare, specific act of decontamination). Cambridge Bible prefers the latter as a distinctive Hebrew concept. |
| Identity of the bullock | A young bull is specified for each day of the seven-day consecration. | Cambridge Bible argues that this bullock is different from the one in vv. 1, 10, 14 (for atoning for the priests), because v. 36 focuses on the altar. Others (e.g., Gill) treat them as the same bullock offered each day. |
| Relevance to Christ's sacrifice | The passage is widely read as typological, prefiguring Christ’s atonement. | The extent of the typology: some see the altar as a direct type of Christ (Calvin, Matthew Henry), while others view it primarily as a ceremonial precedent that underscores the need for a better sacrifice (Clarke). |
Historical & Cultural Context
The altar in view is the brazen altar of burnt offering, located in the Tabernacle courtyard. It was the central meeting point between God and Israel: there sacrifices were made, blood was sprinkled, and atonement was accomplished. But proximity to human sin had consequences. In Israel’s worldview, sin was not only a moral failure but a contaminating force. It could defile objects, land, and even the sanctuary itself. Leviticus 16:18-19 describes the High Priest making atonement for the altar on the Day of Atonement, purging it from the uncleanness of the people. Exodus 29:36-37 extends that principle to the altar’s original consecration, which lasted seven days, a number symbolizing completion and perfection.
The ritual included anointing with the holy oil described in Exodus 30:26-29. This oil, a sacred blend of myrrh, cinnamon, and other spices, set objects apart for God’s service. When Moses anointed the Tabernacle and its furniture (Exodus 40:9, 11, Leviticus 8:10), he consecrated them as holy. The altar, like the priests themselves, needed both cleansing from sin (via the sin offering) and sanctification (via anointing). This double action shows that approach to God requires both forgiveness of sin and a positive setting-apart for His presence. The repetition of the bull offering each day reinforced what later prophets would declare: animal sacrifices could not finally remove sin (Hebrews 10:1, 4). They were a figure, a shadow, anticipating the one sacrifice of Christ.
Textual Notes
The supplied commentaries note no significant textual variants for Exodus 29:36. The Hebrew text is consistent across sources. The Cambridge Bible suggests that the clauses in vv. 36, 37 may have influenced later editorial additions in Leviticus 8:15, but this is a literary rather than a textual observation.
Reception History
Exodus 29:36 has been read through typological lenses from patristic times. Early church fathers saw the altar as a figure of Christ, the place where sacrifice is offered and accepted. In the Reformation, Calvin and Matthew Henry developed this typology explicitly: Christ is both altar and sacrifice, sanctifying himself for His people (John 17:19). The Wesleyan tradition (Clarke, Wesley) focused on the ceremonial cleanliness required for approaching God and the repeated sacrifices pointing to Christ’s single offering. In liturgical traditions, this verse has informed the dedication of church altars and the theology of consecration, though interpretations differ on whether objects can be ‘holy’ in a substantive sense. The verse continues to be cited in discussions of the nature of sin’s contamination and the thoroughness of God’s provision for holiness.
Preaching This Verse
Three-point outline
- Sin infects more than the sinner. The altar needed cleansing because it stood in the presence of a sinful people. Sin’s contamination spreads to objects, spaces, and relationships. We are more entangled with its effects than we realize.
- Holiness is not automatic. The altar did not become holy by its mere existence. It required atonement, anointing, and consecration. Holiness is given through God’s ordained means, not assumed.
- The altar points to Christ. He is both the sacrifice and the place of atonement (Hebrews 13:10). His one offering cleanses permanently, unlike the daily bulls of the old covenant.
Five-point outline
- The daily offering: A bull each day for seven days shows the repetition required under the law and the complete provision of atonement.
- Cleansing the altar: The verb “un-sin” reveals that even objects can be affected by sin’s pollution, a sobering reminder of sin’s reach.
- Anointing for service: The altar was anointed to set it apart, just as Christ was anointed by the Spirit for His ministry (Luke 4:18).
- Atonement for the inanimate: This unusual concept teaches that sin is not only personal but systemic. Our worship and spaces need ongoing purification.
- But one sacrifice: The repeated offerings point to the once-for-all offering of Christ, which cleanses us and our worship perfectly.
Illustration hooks
- A surgical instrument: Before a surgeon operates, the instruments are sterilized. Even a clean table must be prepared. The altar similarly needed ritual purification before it could handle the holy.
- Family heirloom: When a treasured dish is used for the first time after being stored in a dusty attic, it is washed and set apart for special occasions. The altar was treated as something precious and set apart for God’s use.
- A courtroom bench: The judge’s bench is not morally guilty, yet it represents the weight of justice. If the judge is corrupt, the bench seems tainted. The altar, bearing sin offerings, was seen as defiled by the sin it symbolically carried.
Questions your congregation is asking
- Why did an object need forgiveness? Doesn’t God forgive people, not things?
- What does this say about how seriously God views sin, that even the altar needed cleansing?
- How does this Old Testament ritual help me understand Jesus’ sacrifice better?
Leading a Discussion
This verse is part of the detailed instructions for consecrating the altar and priests. It may seem foreign, but it opens a window into how the Bible views sin and holiness. The altar, though an object, was treated as needing atonement. Why? How does this prepare us for the coming of Christ?
Discussion questions
- Read the verse in several translations. What stands out to you about the actions described? (offering, cleansing, anointing)
- The word for “cleanse” in Hebrew literally means “to un-sin.” Why do you think the Bible uses such language for an object?
- Why do you think the ritual had to be repeated for seven days? What does the number seven often symbolize in Scripture?
- Calvin and Gill both see the altar as a type of Christ. In what ways does this ritual foreshadow Jesus’ work?
- How does this passage challenge our modern view of sin as only personal? Are there ways sin can “defile” places or structures?
- If the altar needed preparation before it could be used for worship, what does that suggest about how we approach God?
- How does knowing that Christ is both altar and sacrifice (Hebrews 13:10) change how you read this old covenant ritual?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that the seven-day consecration of the altar likely included a daily physical cleaning before each day's service. The previous day's ashes and residue were removed, keeping the altar fresh and ready for the next stage of sanctification.
Calvin's Commentaries Reformed 1564
Calvin warns that no Old Testament type perfectly matches the reality it foreshadows. The altar's cleansing with blood does not imply impurity in Christ, but rather shows that God is reconciled only through a blood sacrifice. The altar's consecration points to Christ's own sacrifice, which sanctifies believers.
Cambridge Bible for Schools and Colleges Anglican 1880
Cambridge Bible Schools highlights that the Hebrew concept of sin extended beyond people to infect even material objects like the altar. The cleansing ceremony was not merely symbolic purification but actually removing sin from the altar itself, a distinctive idea lost in translations like "cleanse" or "purge."
Geneva Bible Notes Reformed 1599
The Geneva note explains that the daily sin offering of a calf serves specifically for reconciliation, and only after this offering is made is the altar cleansed. The altar must be anointed to be set apart as holy, receiving its sanctification through these prescribed acts.
Gill's Exposition of the Bible Baptist 1748
Gill sees the seven-day repetition of the bullock sin offering as a figure of Christ’s full atonement, which these repeated animal sacrifices could never actually accomplish. He also emphasizes that the altar’s cleansing and anointing prefigure Christ, who as altar bore his people’s guilt and was sanctified for his priestly work.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB highlights that the altar itself was consecrated through cleansing and anointing, just as the priests were. He points out that the altar became holy and forever associated with worship, not merely a tool but a sanctified object in the service of God.
Lange's Commentary Reformed 1857
Lange stresses that the consecration of the priests appears in Exodus rather than Leviticus because the priesthood carries a more universal significance than mere ritual. The prophetic office, represented by Moses, takes the initiative, consecrating Aaron and showing that the prophet stands above the priest in the theocracy.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley draws a parallel between the Old Testament altar's consecration and Christ's role as our altar. Just as the altar was set apart and made holy enough to sanctify the gifts placed on it, Christ sanctified Himself so that believers and their offerings might be made acceptable to God.
