Preparation: The Priest Who Must Come Humbly
God's first instruction about the Day of Atonement is a prohibition:
"Tell Aaron your brother not to come at any time into the Holy Place inside the veil, before the mercy seat that is on the ark, so that he may not die. For I will appear in the cloud over the mercy seat."
— Leviticus 16:2 (ESV)
Aaron may not enter whenever he chooses. He may not enter because he feels called, or because the people need something, or because he has prayed with special intensity. He may enter the Most Holy Place only on this one day each year, only after following an exact sequence, and only with the specific provisions God has required. Access to the innermost presence of God is entirely God's to grant, on God's terms.
The high priest's garments for this day are deliberately different from his ordinary vestments. On every other day of ministry, Aaron wears the elaborate robes described in Exodus 28 — the ephod with its onyx stones, the breastpiece with its twelve gems and the names of Israel's tribes, the robe with its golden bells and pomegranates, the turban with its gold plate inscribed "Holy to the LORD." These garments are splendid. They are made for glory and for beauty. On the Day of Atonement, Aaron removes all of it. He washes in water and puts on plain white linen: linen tunic, linen undergarment, linen sash, linen turban. The garments of a servant, not an official. Gordon Wenham observes that this exchange is theologically telling — on the day of maximum atonement, the mediator strips away visible glory and comes before God as a humble servant, representing a people who have accumulated a year's worth of failure.
Before he can enter on behalf of the people, Aaron must offer atonement for himself and his household. He takes a bull as a sin offering and a ram as a burnt offering. He slaughters the bull and takes its blood behind the veil, and first the incense: he fills a censer with coals from the altar and heaps frankincense on them, then carries the smoking censer into the Most Holy Place so the cloud of incense covers the mercy seat. Even the high priest does not approach the ark directly. The cloud of incense provides a protective veil between Aaron and the full exposure of divine presence. Matthew Henry observes that the incense smoke functions as a mediating buffer — even the mediator requires mediation in the innermost room.
We find it significant that before Aaron can do anything for anyone else, he must first offer atonement for himself. The high priest is not exempt from the problem he is called to address. He is the most qualified person in Israel to approach the Most Holy Place, and he still has to offer a bull for his own sin before he can represent the nation. There is something deeply right about that. No one stands before God on the basis of their own superior righteousness, not even the high priest.
The First Goat: Blood That Cleanses the Sanctuary
After taking the bull's blood behind the veil and sprinkling it once on the front of the mercy seat and seven times before it — making atonement for himself and his household — Aaron turns to the congregation's offering. Two male goats have been brought to the entrance of the tent, and lots are cast over them: one lot for the LORD, one lot for Azazel. The goat on which the LORD's lot falls is slaughtered as a sin offering for the people. Aaron takes its blood behind the veil and does with it as he did with the bull's blood — sprinkling it on and before the mercy seat, making atonement for the Most Holy Place because of Israel's uncleanness and transgressions.
Aaron then comes out to the altar that stands in the outer court and applies blood there too: some of the bull's blood and some of the goat's blood, put on the horns of the altar and sprinkled seven times. The sequence is critical: the blood moves from the innermost space outward — Most Holy Place, then Holy Place, then the courtyard altar. The entire sanctuary, from center to periphery, is cleansed.
John Hartley, in his Word Biblical Commentary, observes that this progressive cleansing from inside out reflects how the sanctuary became defiled: Israel's sins accumulated inward from the outer altar through to the innermost chamber over the course of a year. The blood of the Day of Atonement reverses that accumulation, clearing the house from its most polluted center outward. Allen Ross notes that the two aspects of the ceremony together — blood applied to the mercy seat and blood applied to the outer altar — show that the Day of Atonement addresses the entire sacrificial structure, not just one element of it.
What we keep coming back to is the direction of the movement: inside out. God's house is cleansed from its most sacred center outward. The defilement that accumulated was not merely on the surface — it reached the mercy seat, the innermost place of God's presence. The blood has to go all the way in to deal with it. That is the picture the Day of Atonement gives us of how serious the problem of sin is: it reaches the holiest place, and only blood can address it there.
The Second Goat: Sins Carried Away
The second goat has been standing alive at the entrance of the tent throughout Aaron's work inside. Now Aaron comes out, lays both his hands on the head of the live goat, and confesses:
"Aaron shall lay both his hands on the head of the live goat, and confess over it all the iniquities of the people of Israel, and all their transgressions, all their sins. And he shall put them on the head of the goat and send it away into the wilderness by the hand of a man who is in readiness. The goat shall bear all their iniquities on itself to a remote area, and he shall let the goat go free in the wilderness."
— Leviticus 16:21–22 (ESV)
The two goats together accomplish what neither goat alone could accomplish. The first goat's blood deals with the pollution that sin creates in the sanctuary — it cleanses the house where God lives. The second goat deals with something else: the burden of sin carried by the people, their accumulated transgressions and iniquities. Aaron's two-handed laying of hands — the more emphatic form of the gesture — transfers the full weight of Israel's sin to the goat. A designated man takes the goat out into the wilderness, beyond the camp, to a remote and uninhabited region, and releases it. The goat is not killed. It disappears into the wilderness, carrying what it bears away from the camp.
Allen Ross observes that the two goats together present a complete picture of what atonement involves: sin is both covered through blood applied to the sanctuary, and removed from the midst of the people. The imagery of removal, of transgressions carried far away, becomes one of the most enduring pictures in the Hebrew Bible. Psalm 103:12 will capture it: "As far as the east is from the west, so far does he remove our transgressions from us." Micah 7:19 will speak of sins cast into the depths of the sea. The scapegoat ceremony is the dramatic, enacted source of that language.
The scapegoat is one of those images that has seeped into the broader culture in ways that strip it of its meaning. In common usage, a scapegoat is an innocent person blamed for something they didn't do. But in Leviticus, the goat carries something real. It carries the genuine, confessed, named sins of the whole nation — not a false accusation, but the actual accumulated failure of a year's worth of unfaithfulness. It disappears into the wilderness bearing what is really there. And the people are genuinely left lighter for it.
Israel's Sabbath of Solemn Rest
The ceremony does not end with the goat's release. Aaron returns to the tent, removes his linen garments, bathes, puts his regular robes back on, and then offers the burnt offerings for himself and for the people — completing the day's sacrificial work. The man who led the goat into the wilderness must also wash before returning to the camp. When everything is finished, it is evening.
For the people, the entire day is to be marked differently from every other day of the year:
"And this shall be a statute forever for you, that atonement may be made for the people of Israel once in the year because of all their sins."
— Leviticus 16:34 (ESV)
Israel fasts — "afflicts themselves" — throughout the day while the high priest works. All regular labor ceases. It is called a Sabbath of solemn rest. But unlike the weekly Sabbath, which is marked by the peace offerings and feasting, this Sabbath is marked by fasting and mourning. The people sit with the weight of what they are: a community who, despite the daily offerings and the Sabbaths and the feasts, continues to accumulate the defilement of sin and requires an annual, comprehensive cleansing before they can continue in God's presence.
Iain Duguid notes that the annual character of the Day of Atonement is, in itself, a theological statement. The ceremony works — it accomplishes real cleansing — but it must be repeated. Next year, the same defilement will have accumulated, and the high priest will go behind the veil again. This repetition is not a deficiency in the ceremony but an honest acknowledgment of what it is addressing: the ongoing problem of human sinfulness in the presence of a holy God. The book of Hebrews will use exactly this repetition as its argument: the annual Day of Atonement could never finally resolve what it addressed, because it had to keep being done. The contrast is with the new covenant high priest, who entered the true Most Holy Place not with animal blood but with his own — "once for all" (Hebrews 9:12).
We find that contrast in Hebrews not as a dismissal of what Leviticus 16 was doing, but as its completion. The Day of Atonement was not a failed ceremony. It was a real provision that genuinely cleansed the sanctuary and genuinely removed Israel's sins — and it was also a picture, pointing forward to something that could accomplish what the annual repetition could never permanently settle. One high priest, once, behind a veil that tore from top to bottom. We keep coming back to that. Leviticus 16 sets the frame that makes the cross legible.
