What Happened on the Day of Atonement? Why Did the High Priest Enter with Blood?
Leviticus 16 describes the most solemn day in Israel’s calendar: the Day of Atonement. On this day alone, the high priest entered the Holy of Holies with sacrificial blood. Two goats were presented — one slain, one sent away. Sin was symbolically covered, removed, and judged.
This moment represents the theological climax of the Old Testament sacrificial system. As traced throughout The Blood in Scripture, blood progressively unfolds as covering, covenant seal, protection from judgment, and ratification. In Leviticus 16, it becomes the central means of national cleansing and priestly mediation.
Direct Answer: What Happened on the Day of Atonement?
- The high priest offered sacrifices for himself and the people (Leviticus 16:6, 15).
- One goat was killed; its blood was sprinkled on the mercy seat.
- The second goat (the scapegoat) bore the sins of Israel into the wilderness.
- The ritual symbolized both satisfaction of divine justice and removal of guilt.
- The event foreshadowed Christ’s once-for-all atoning work (Hebrews 9–10).
Sin was covered — and carried away.
Why Was the Day of Atonement Necessary?
Israel lived under covenant with God (Exodus 24). They had been redeemed through Passover blood (Exodus 12). Yet sin persisted within the covenant community.
Leviticus 16:16 explains the purpose:
“Thus he shall make atonement for the Holy Place, because of the uncleannesses of the people of Israel…” (ESV)
Sin not only corrupted individuals — it defiled sacred space. The Day of Atonement cleansed both people and sanctuary.
What Is the Role of the High Priest?
Only the high priest could enter the Most Holy Place — and only once per year. Leviticus 16:2 warns:
“Tell Aaron your brother not to come at any time into the Holy Place inside the veil… so that he may not die.” (ESV)
Access to God’s immediate presence required blood and mediation.
The high priest first offered a bull for his own sins (16:6). Even the mediator required atonement. This highlights the imperfection of the Old Covenant priesthood.
A perfect High Priest would not.
Why Were There Two Goats?
Leviticus 16:7–10 introduces two goats presented before the LORD. Lots were cast — one “for the LORD,” one “for Azazel” (often translated scapegoat).
The First Goat: Propitiation
The first goat was slain. Its blood was brought inside the veil and sprinkled on the mercy seat (16:15).
This act addressed divine justice. Blood satisfied the covenant requirement that sin brings death.
Propitiation refers to the turning away of wrath through sacrifice. The slain goat symbolized judgment borne by a substitute.
The Second Goat: Expiation
Leviticus 16:21–22 describes the second goat:
“And Aaron shall lay both his hands on the head of the live goat, and confess over it all the iniquities of the people… and send it away into the wilderness.” (ESV)
This goat was not killed immediately. It carried sin away, symbolizing removal.
Expiation refers to the removal of guilt. The scapegoat visually dramatized sin being taken far from the people.
One goat removed guilt.
What Is the Mercy Seat?
The mercy seat (Hebrew: kapporet) was the cover of the Ark of the Covenant. It represented the place where God’s presence dwelt between the cherubim (Exodus 25:22).
Blood sprinkled on the mercy seat symbolized atonement made before God’s throne.
Romans 3:25 uses the Greek term hilastērion, often translated “propitiation,” which also refers to the mercy seat. Paul identifies Christ Himself as the true mercy seat — the place where justice and mercy meet.
In Christ, the mercy seat came to us.
How Does Hebrews Interpret the Day of Atonement?
Hebrews 9 explains that the high priest entered yearly “not without taking blood” (Hebrews 9:7, ESV).
Yet Hebrews 9:12 contrasts Christ:
“He entered once for all into the holy places… by means of his own blood, thus securing an eternal redemption.” (ESV)
The Old Covenant ritual was repeated annually. Christ’s sacrifice was once for all.
Hebrews 10:4 adds:
“For it is impossible for the blood of bulls and goats to take away sins.” (ESV)
The Day of Atonement symbolized cleansing but did not permanently remove sin. It pointed forward.
How Does This Fulfill the Pattern We Have Seen?
- Genesis 3 — covering through death.
- Abel — acceptable sacrifice by faith.
- Abraham — covenant sealed and substitute provided.
- Passover — blood protects from judgment.
- Exodus 24 — covenant ratified by blood.
- Leviticus 16 — blood cleanses and removes sin.
The pattern intensifies. Blood is central at every stage.
Why Does This Matter for Believers Today?
The Day of Atonement teaches that sin is serious and access to God is costly. It also teaches that God provides a means of cleansing.
Christ fulfills both goats in one person. His death satisfies divine justice. His sacrifice removes guilt completely.
Hebrews 10:14 declares:
“For by a single offering he has perfected for all time those who are being sanctified.” (ESV)
Christ’s blood secures eternal redemption.
