Ezekiel 43:18: Altar purification's role?
How does Ezekiel 43:18 emphasize the importance of altar purification in worship?

Reading the Text

“Then He said to me: ‘Son of man, this is what the Lord GOD says: These are the statutes for the altar on the day it is built, so that burnt offerings may be offered on it and blood sprinkled against it.’” (Ezekiel 43:18)


Key Observation: Purification Comes Before Worship

Ezekiel 43:18 begins a detailed section (vv. 18-27) describing how the altar must be cleansed before any sacrifice is accepted.

• The verse puts the spotlight on “statutes”—fixed, non-negotiable rules handed down by the Lord GOD.

• The goal is explicit: the altar is only “ready” for burnt offerings and blood once it has been purified.


Why the Altar Must Be Purified

1. Holiness of God

• God’s glory had just returned to the temple (43:1-5). A holy God requires a holy meeting place.

Exodus 29:36-37 establishes the precedent: “You must purify the altar… and the altar shall be most holy”.

2. Atonement for Sin

• Blood sprinkled on the altar (v. 18) points to substitutionary atonement (Leviticus 17:11).

• Purification rituals acknowledge sin’s defilement and God’s provision for cleansing.

3. Protection for Worshipers

Leviticus 16:18-19 shows that purification protects the people from judgment when approaching God.

• Without cleansing, worshipers would be exposed to holy wrath (cf. Isaiah 6:5-7).


Old Testament Echoes

Leviticus 8:10-15 – Moses consecrates the altar with anointing oil and blood.

2 Chronicles 29:18-21 – Hezekiah’s priests cleanse the altar before national worship is restored.

Numbers 7:10-88 – Tribal leaders present offerings only after the altar’s dedication.


New Testament Fulfillment

Hebrews 9:22 – “Without the shedding of blood there is no forgiveness.”

Hebrews 9:14 – Christ’s blood “will cleanse our consciences” just as the altar was cleansed.

1 Peter 1:18-19 – The Lamb “without blemish” fulfills every Old Testament purification.


Practical Takeaways for Worship Today

• God still cares about purity in worship; He now purifies hearts (1 Corinthians 3:16-17).

• Approach Him through the once-for-all sacrifice of Christ, the perfect altar and offering (Hebrews 10:19-22).

• Maintain a lifestyle of holiness that matches the purity God requires (1 Peter 1:15-16).
