Matthew Henry
From his Commentary on the Whole Bible. Henry comments on passages, not single verses — this entry covers Exodus 30:1–10. His two-level outline is real structure in the source text, so it is rendered as structure.
I.The orders given concerning the altar of incense are,
1.That it was to be made of wood, and covered with gold, pure gold, about a yard high and half a yard square, with horns at the corners, a golden cornice round it, with rings and staves of gold, for the convenience of carrying it, Exo 30:1-5. It does not appear that there was any grate to this altar for the ashes to fall into, that they might be taken away; but, when they burnt incense, a golden censer was brought with coals in it, and placed upon the altar, and in that censer the incense was burnt, and with it all the coals were taken away, so that no coals nor ashes fell upon the altar. The measure of the altar of incense in Ezekiel's temple is double to what it is here (Eze 41:22), and it is there called an altar of wood, and there is no mention of gold, to signify that the incense, in gospel times, should be spiritual, the worship plain, and the service of God enlarged, for in every place incense should be offered, Mal 1:11.
2.That it was to be placed before the veil, on the outside of that partition, but before the mercy-seat, which was within the veil, Exo 30:6. For though he that ministered at the altar could not see the mercy-seat, the veil interposing, yet he must look towards it, and direct his incense that way, to teach us that though we cannot with our bodily eyes see the throne of grace, that blessed mercy-seat (for it is such a throne of glory that God, in compassion to us, holds back the face of it, and spreads a cloud upon it), yet we must in prayer by faith set ourselves before it, direct our prayer, and look up.
3.That Aaron was to burn sweet incense upon this altar, every morning and every evening, about half a pound at a time, which was intended, not only to take away the ill smell of the flesh that was burnt daily on the brazen altar, but for the honour of God, and to show the acceptableness of his people's services to him, and the pleasure which they should take in ministering to him, Exo 30:7, Exo 30:8. As by the offerings on the brazen altar satisfaction was made for what had been done displeasing to God, so, by the offering on this, what they did well was, as it were, recommended to the divine acceptance; for our two great concerns with God are to be acquitted from guilt and accepted as righteous in his sight.
4.That nothing was to be offered upon it but incense, nor any incense but that which was appointed, Exo 30:9. God will have his own service done according to his own appointment, and not otherwise.
5.That this altar should be purified with the blood of the sin-offering put upon the horns of it, every year, upon the day of atonement, Exo 30:10. See Lev 16:18, Lev 16:19. The high priest was to take this in his way, as he came out from the holy of holies. This was to intimate to them that the sins of the priests who ministered at this altar, and of the people for whom they ministered, put a ceremonial impurity upon it, from which it must be cleansed by the blood of atonement.
II.This incense-altar typified,
1.The mediation of Christ. The brazen altar in the court was a type of Christ dying on earth; the golden altar in the sanctuary was a type of Christ interceding in heaven, in virtue of his satisfaction. This altar was before the mercy-seat; for Christ always appears in the presence of God for us; he is our advocate with the father (Jo1 2:1), and his intercession is unto God of a sweet-smelling savour. This altar had a crown fixed to it; for Christ intercedes as king. Father, I will, Joh 17:24.
2.The devotions of the saints, whose prayers are said to be set forth before God as incense, Psa 141:2. As the smoke of the incense ascended, so much our desires towards God rise in prayer, being kindled with the fire of holy love and other pious affections. When the priest was burning incense the people were praying (Luk 1:10), to signify that prayer is the true incense. This incense was offered daily, it was a perpetual incense (Exo 30:8); for we must pray always, that is, we must keep up stated times for prayer every day, morning and evening, at least, and never omit it, but thus pray without ceasing. The lamps were dressed or lighted at the same time that the incense was burnt, to teach us that the reading of the scriptures (which are our light and lamp) is a part of our daily work, and should ordinarily accompany our prayers and praises. When we speak to God we must hear what God says to us, and thus the communion is complete. The devotions of sanctified souls are well-pleasing to God, of a sweet-smelling savour; the prayers of saints are compared to sweet odours (Rev 5:8), but it is the incense which Christ adds to them that makes them acceptable (Rev 8:3), and his blood that atones for the guilt which cleaves to our best services. And, if the heart and life be not holy, even incense is an abomination (Isa 1:13), and he that offers it is as if he blessed an idol, Isa 66:3.
Historical interpretation
Historical Reception
One surviving comment on this verse from the historical church.
Therefore, if I should consider how the true “high priest,” my Lord Jesus Christ, having indeed been placed in the flesh, was with the people all year, that year about which he himself says, “He sent me to proclaim good news to the poor and to announce the acceptable year of the Lord and the day of forgiveness,” I perceive how “once” in this “year” on the Day of Atonement he enters into “the Holy of Holies.” That is, when with his dispensation fulfilled “he penetrates the heavens” and goes to the Father to make atonement for the human race and prays for all those who believe in him. Knowing this atonement by which he propitiates the Father for humans, the apostle John says, “I say this, little children, that we may not sin. But if we should sin, we have an advocate before the Father, Jesus Christ the just; and he himself is the propitiation for our sins.” But Paul also in a similar way mentions this atonement when he says concerning Christ, “Whom God appointed as a propitiator by his blood through faith.” Therefore the Day of Atonement remains for us until the sun sets; that is, until the world comes to an end.

Summary
Exodus 30:10 meticulously details the annual atonement ritual for the Altar of Incense, stipulating that Aaron, in his role as High Priest, must apply the blood of the sin offering to its horns once a year. This command, to be observed perpetually throughout Israelite generations, profoundly underscores the altar's supreme sanctity, declaring it "most holy unto the LORD," and highlights the foundational biblical truth that even sacred objects required regular purification through blood to maintain their fitness for divine presence amidst a sinful people.
Context
Literary Context
This verse serves as the concluding instruction for the Altar of Incense, a significant piece of Tabernacle furniture described in Exodus 30:1-10. Prior verses detail its construction from acacia wood overlaid with pure gold, its dimensions, and its strategic placement in the Holy Place, directly before the veil that separated it from the Most Holy Place, where the Ark of the Covenant resided. Exodus 30:7-8 outlines the High Priest Aaron's daily duty to burn fragrant incense upon it, morning and evening, symbolizing the rising prayers and worship of God's people. The annual atonement ritual prescribed in Exodus 30:10 acts as a critical counterpoint to this daily activity, emphasizing that even an object used for holy communion required periodic purification. This necessity arose from its contact with sinful priests and its location within a Tabernacle surrounded by a sinful community, thereby maintaining the purity required for God's holy presence. This ritual also anticipates the more comprehensive atonement ceremonies detailed in Leviticus 16.
Historical & Cultural Context
The ritual mandated in Exodus 30:10 was an indispensable component of the annual Day of Atonement, known as Yom Kippur, which was the most solemn and significant day in the Israelite liturgical calendar. On this sacred day, the High Priest meticulously performed a series of elaborate rituals designed to atone for the sins of the entire Israelite community and to ritually purify the Tabernacle and all its sacred furnishings from any defilement or impurity accumulated throughout the preceding year. The ancient Israelite understanding of "holiness" encompassed being set apart exclusively for God's use, but it also implied a susceptibility to defilement through sin or ritual impurity. Consequently, even objects consecrated to God, though inherently holy, could become ritually unclean through human interaction, necessitating a prescribed purification ritual. The application of blood, understood as the essence of life, was the divinely ordained means of cleansing and consecration, as explicitly stated in Leviticus 17:11. This annual purification of the Altar of Incense, alongside other elements of the Tabernacle, profoundly underscored the pervasive nature of sin and the constant, gracious provision of atonement by God to sustain His holy presence amidst His people.
Key Themes
Exodus 30:10 contributes significantly to several overarching themes within the book of Exodus and the broader Pentateuch. Foremost among these is the theme of God's absolute holiness and His demand for purity in all that approaches Him. The altar's designation as "most holy" (H6944) highlights this divine attribute and the strict requirements for maintaining a relationship with a holy God. Secondly, the verse underscores the pervasive nature of sin and its defiling effect, even on sacred objects and spaces. Despite its divine consecration, the altar required annual cleansing because it existed within a sinful human context. Thirdly, the theme of atonement through blood is central, emphasizing the principle that sin demands a life (represented by blood) to cover or expiate it (Leviticus 17:11). This ritualistic cleansing points to God's gracious provision for reconciliation. Finally, the verse subtly introduces the theme of foreshadowing, as the repeated, annual nature of this atonement ritual implicitly highlights its temporary and incomplete nature, thereby anticipating the need for a perfect, once-for-all sacrifice that would fully and eternally cleanse both people and sacred space, a concept more fully developed in the New Testament, particularly in Hebrews 9.
Exposition and Analysis
Key Word Analysis
The Hebrew verb כָּפַר (kâphar), a primitive root, means "to cover," "to expiate," "to condone," "to placate," or "to cancel." In the context of the Old Testament sacrificial system, it signifies the divine act of covering or purging sin, thereby making it possible for a holy God to dwell among His sinful people without consuming them. It implies a restoration of a right relationship through divine cleansing and reconciliation.
The word קֶרֶן (qeren), meaning "horn," refers to the four prominent projections at the corners of the altar. In the ancient Near East, horns often symbolized strength, power, and authority. They could also serve as a place of refuge or asylum (e.g., 1 Kings 1:50). Applying blood to the horns of the altar signified the complete consecration and purification of its power and function, ensuring that its entire purpose was set apart for God's holy use.
The Hebrew word קֹדֶשׁ (qôdesh), typically appearing as the superlative phrase qodesh qodashim ("holiness of holies" or "most holy thing"), denotes the highest possible degree of sanctity. It signifies something utterly set apart, consecrated, and inviolable, exclusively for God. This designation emphasizes God's absolute holiness and His demand for supreme purity in all that approaches Him or is dedicated to His service.
Verse Breakdown
"And Aaron shall make an atonement upon the horns of it once in a year"
This clause precisely identifies the agent of the ritual, Aaron, the High Priest, who acts as the divinely appointed mediator. The action is "make an atonement" (H3722, kâphar), signifying the covering or expiation of sin. The specific location for this application is "upon the horns" (H7161, qeren) of the Altar of Incense, symbolizing the complete purification of its power and function. The frequency is explicitly stated as "once in a year" (H259, ʼechâd; H8141, shâneh), highlighting the recurring, yet temporary, nature of the Old Covenant cleansing.
"with the blood of the sin offering of atonements"
This segment specifies the indispensable means of atonement: "the blood" (H1818, dâm) derived "of the sin offering" (H2403, chaṭṭâʼâh). The sin offering was a specific sacrifice designed to atone for unintentional sins and ritual impurities, thereby restoring the covenant relationship. The phrase "of atonements" (H3725, kippur) further emphasizes that this blood was specifically for the purpose of making expiation and reconciliation. The shedding of blood was paramount, signifying that life was given to cover sin, based on the principle that "the life of the flesh is in the blood."
"once in the year shall he make atonement upon it throughout your generations"
This reiterates the annual requirement, reinforcing its fixed regularity and emphasizing its perpetual nature as a divine ordinance. The phrase "throughout your generations" (H1755, dôwr) signifies that this command is binding for all future generations of Israel, underscoring the enduring importance and necessity of this ritual within the covenant relationship.
"it [is] most holy unto the LORD"
This concluding declaration provides the ultimate theological rationale for the entire ritual. The altar's supreme holiness (H6944, qôdesh), its being utterly set apart for Yahweh (H3068, Yᵉhôvâh), necessitated this annual purification. It profoundly underscores God's character as perfectly holy and His unwavering demand for absolute purity in His presence and in all that serves Him.
Literary Devices
Exodus 30:10 employs several potent literary devices to convey its profound theological message. Repetition is prominently featured with the phrase "once in a year," which appears twice within the verse, powerfully emphasizing the fixed, unalterable, and recurring nature of this vital annual ritual. This repetition underscores both its importance and the continuous need for atonement under the Old Covenant. The phrase "throughout your generations" functions as a merism or a statement of totality, signifying that this command is binding for all time, from one generation to the next, highlighting the enduring nature of God's covenant requirements. The concluding declaration, "it [is] most holy unto the LORD," utilizes superlative language (the Hebrew "holiness of holies" or "most holy") to intensely emphasize the altar's profound sacredness and its exclusive dedication to God. This strong declaration serves as a theological emphasis, providing the ultimate reason for the meticulous atonement ritual—God's absolute holiness demands absolute purity in His presence. Furthermore, the entire ritual itself is deeply symbolic, with the blood representing life given for cleansing and expiation, and the horns representing the altar's power, strength, and refuge, all of which require purification to be fit for holy service.
Theological and Thematic Connections
Exodus 30:10 profoundly illustrates several core theological truths central to biblical revelation. It highlights God's absolute holiness and His unyielding demand for purity, even in objects dedicated to His service, thereby revealing the pervasive nature of sin and its defiling effect on everything it touches. The necessity of blood for atonement underscores the principle that sin requires a life to be given as a covering, a testament to the gravity of human transgression and the immense cost of reconciliation with a holy God. The annual, repeated nature of this ritual also points to its inherent inadequacy to provide a final, perfect cleansing, thereby foreshadowing the need for a superior, once-for-all sacrifice that would truly and eternally cleanse.
Reflection and Application
The ancient ritual of atoning for the Altar of Incense, though seemingly distant from our modern experience, offers profound and enduring insights for contemporary believers. It serves as a stark reminder that God's holiness remains an unchanging attribute, demanding reverence, purity, and a humble approach in all our interactions with Him. Just as the altar, despite its sacred purpose and divine consecration, required annual cleansing due to its contact with a sinful world and sinful priests, so too our lives—even our most sincere acts of worship, service, and prayer—are tainted by the pervasive reality of sin and require continuous purification. This verse should cultivate within us a deep and abiding appreciation for the finished work of Jesus Christ, whose singular, perfect sacrifice has accomplished what countless Old Testament rituals could only foreshadow: a complete, eternal, and definitive cleansing. We are now graciously invited to approach God not through repeated rituals or the mediation of a fallible human high priest, but directly and boldly through the precious blood of Jesus, our perfect High Priest, whose righteousness alone makes our prayers and lives acceptable to the Most Holy God. This profound truth should inspire both profound humility concerning our own sinfulness and immense gratitude for God's boundless grace and perfect provision in Christ.
Questions for Reflection
FAQ
Why did even a holy object like the Altar of Incense need atonement?
The Altar of Incense, though consecrated for sacred use and located in the Holy Place, was handled daily by sinful priests and existed within the Tabernacle, which was pitched in the midst of a sinful community. According to the Old Covenant understanding of ritual purity, anything in contact with sin or impurity could become defiled. The annual atonement ritual, particularly on the Day of Atonement (Leviticus 16), was necessary to cleanse the Tabernacle and its furnishings from any ritual impurity accumulated throughout the year, ensuring that God's holy presence could continue to dwell among His people without consuming them. This ritual served as a constant reminder of the pervasive nature of sin and God's absolute holiness, demonstrating that even the instruments of worship required divine cleansing to remain fit for service.
What was the significance of applying blood to the "horns" of the altar?
The horns on the four corners of the altar were symbolic of strength, power, and authority in ancient Near Eastern cultures. They could also serve as a place of refuge. Applying the blood of the sin offering to these horns signified a complete and thorough purification of the altar's entire function and inherent power. It meant that the altar, in its full capacity—to facilitate the prayers and worship of Israel—was consecrated and cleansed, ensuring its purpose was set apart and made acceptable to God. This act underscored that even the altar's "strength" or "authority" in mediating worship was entirely dependent on God's provision of atonement through the shedding of blood, as stated in Leviticus 17:11.
Christ-Centered Fulfillment
Exodus 30:10, with its emphasis on annual atonement through blood for a "most holy" object, powerfully foreshadows the ultimate and perfect work of Jesus Christ. The repeated, temporary nature of the Old Covenant sacrifices, including the annual cleansing of the Altar of Incense, highlighted their inherent inadequacy to provide a final solution for sin. As the author of Hebrews explicitly states, the Law's sacrifices could never "make perfect those who draw near" (Hebrews 10:1). This constant need for re-atonement pointed to a future, superior sacrifice. Jesus Christ is the fulfillment of this shadow, serving as both the perfect High Priest and the spotless Lamb of God. Unlike Aaron, who offered sacrifices repeatedly, Christ "entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption" (Hebrews 9:12). His blood, shed on the cross, cleanses not merely an altar, but the consciences of believers from dead works to serve the living God (Hebrews 9:14). The "most holy" nature of the altar, requiring purification, finds its ultimate counterpart in Christ, who is inherently holy and whose singular sacrifice perfectly satisfies God's righteous demands, making our prayers and lives eternally acceptable to God through His complete and all-sufficient work (Hebrews 10:10-14).
