What Is an Altar? Exodus 20:24-26 Explained Plainly
Short answer: An altar is a raised structure on which sacrifice is offered to God, and in Scripture it is also the place where God promises to meet with his people. In Exodus 20:24-26 God tells Israel, You shall make an altar of earth for me, and shall sacrifice on it your burnt offerings and your peace offerings, your sheep and your cattle. In every place where I record my name I will come to you and I will bless you. So an altar is not a magic object or a location with power in itself. It is the appointed meeting point between a holy God and a sinful people, where a life is given and fellowship is restored. The altar matters because of the sacrifice offered on it and the God who receives it, not because of its stones or its size.
An altar is a place of sacrifice, not a religious decoration
The first thing Exodus 20:24 establishes is purpose. God does not say build an altar so you have something impressive to look at. He says make an altar of earth for me, and shall sacrifice on it your burnt offerings and your peace offerings. The altar exists for the offering. The burnt offering expressed complete consecration to God; the peace offering expressed fellowship and thanksgiving shared before him. Both required a life to be given. This is why an altar without sacrifice is meaningless in the Old Testament. A pile of uncut stones in a field accomplishes nothing. The altar is defined by what happens on it.
This shapes how we read every altar story in Scripture. Noah built an altar to Yahweh and offered burnt offerings on the altar, as Genesis 8:20 records. Abram, Isaac, Jacob, Moses, Joshua, Gideon, Samuel, David, and Elijah all built or repaired altars, and in every case the altar is tied to an encounter with God that includes offering. When 1 Kings 18:30 says Elijah repaired Yahweh's altar that had been thrown down, the repair was not the point; the point was the sacrifice and prayer that followed on it. An altar is a working place, not a monument.
Practically, this guards us from treating church buildings, communion tables, or devotional corners as altars in the biblical sense. A table is not an altar because someone calls it one. In the Old Covenant, the altar was the God-given location for the God-given sacrifice. In the New Covenant, the sacrifice has already been offered once for all, so there is no remaining command to build altars for sacrifice. We still come to God, but we come through Christ, not through a structure we construct. The vocabulary of altar in the New Testament is used carefully, and we should be careful with it too.
That does not make the altar theme irrelevant. It makes it diagnostic. Whenever people in Scripture drift from God, the altars fall into disrepair or get mixed with idolatry. Whenever there is revival, altars are rebuilt and true worship resumes. The altar is a barometer of covenant faithfulness. If we ask what is the state of our own fellowship with God, one honest question is whether we have abandoned the place of sacrifice, the cross, for something more comfortable. The altar preaches that sin costs, and that approaching God is never casual.
Earth and uncut stone: why the materials matter
Exodus 20:24 specifies an altar of earth. The next verses, though not all quoted here, go on to speak of stone altars made of uncut stones, and they forbid steps that would expose nakedness. The instruction is deliberately humbling. Earth is what you walk on. It is available to the poorest Israelite and requires no skill. God is not asking for architecture; he is asking for obedience. A dirt altar says the worshipper brings nothing impressive and depends entirely on God's acceptance. The altar's plainness is part of its message: the value lies in the sacrifice and the God who receives it, not in the craft of the builder.
Uncut stones carry the same logic. If a worshipper chisels and polishes the stones, the altar begins to look like human achievement. Other ancient religions built elaborate raised platforms, carved images, and ornamental steps, and Israel was surrounded by them. God forbids imitation of those patterns. His altar is to be simple so that no one boasts. This is a recurring biblical principle: God chooses the lowly and the ordinary so that the glory goes to him. The altar of earth is a visual parable of grace, and it prepares us for a gospel where salvation comes not by human craftsmanship but by God's provision.
Read against the second commandment, which immediately precedes this passage, the point sharpens. Israel is not to make carved images or bow to them. An altar decorated with religious art and used as a focal point for devotion would slide toward exactly what was forbidden. So the altar must stay plain. The place of sacrifice must not compete with the sacrifice. When religion becomes impressive, it often becomes self-referential. The dirt altar keeps the focus where it belongs. It is a physical reminder that we bring nothing to God that he needs, and that he accepts us on his terms, not ours.
There is pastoral wisdom here. We are tempted to make our worship impressive, our giving visible, our service polished. None of that is wrong in itself, but it can quietly become the altar we trust. The earth altar asks a searching question: if everything impressive were stripped away, would we still come to God for mercy? Would we still bring the sacrifice of a broken and contrite heart? The simplicity of the altar is a call to honesty. It tells us that God is not impressed by our platforms, but he does receive the offerings of those who come to him in humility and faith.
The surpassing promise: I will come to you and I will bless you
The heart of Exodus 20:24 is not the command to build but the promise attached to it. God says, In every place where I record my name I will come to you and I will bless you. The altar is where God causes his name to be remembered, and where he promises his presence and blessing. This is staggering. The holy God of Sinai, who speaks from fire and thick darkness, commits to meet with his people at a dirt altar. He does not merely permit worship; he promises to attend it. The altar is a meeting place because God says so.
Notice the breadth of the promise. In every place where I record my name. Before the temple existed, before there was one central sanctuary, God promised to meet his people wherever his name was honored. That anticipates the tabernacle, then the temple, and finally the truth that God's presence is not bound to a single location. It also warns against superstition. The altar has no power in itself; God's presence is the gift. When Israel later treated the ark or the temple as a talisman, they were rebuked. The blessing flows from God's gracious commitment, not from the object or the ground.
This promise also foreshadows the New Covenant. Jesus told the Samaritan woman that true worshippers would worship the Father in spirit and truth, not on this mountain or in Jerusalem. Hebrews 13:10 says, We have an altar from which those who serve the holy tabernacle have no right to eat. That altar is not a physical structure; it is Christ himself, the sacrifice once offered. The promise of meeting and blessing now attaches to him. The altar theme reaches its goal in the cross, where God's name is supremely recorded and where we are met with mercy rather than judgment.
So the altar should produce expectation in us, not nostalgia. If God promises to meet his people where his name is recorded, we should come to worship expecting him to speak, convict, comfort, and bless. Not because of a building or a ritual, but because he has promised. At the same time we must not manufacture emotional experiences or claim divine encounters that God has not promised. The promise is tied to his name and his word. Where the gospel is proclaimed and the sacrifice of Christ is honored, there we may expect the living God to come to us and bless us.
Noah, Elijah, and the long history of altars built and rebuilt
Genesis 8:20 tells us that Noah built an altar to Yahweh and offered burnt offerings on it after the flood. The altar appears very early in Scripture, before the law, before the tabernacle, before any command about earth or stone. This shows that the impulse to approach God through sacrifice is ancient and human, yet always guided by God's initiative in accepting it. Noah's altar is a response of gratitude after judgment and rescue. It is a picture of the pattern that runs through Scripture: God saves, and his people respond in worship that costs them something.
By Elijah's day the altars had been thrown down. First Kings 18:30 says, He repaired Yahweh's altar that had been thrown down. Years of apostasy under Ahab and Jezebel had left true worship in ruins. Elijah did not build a new religion; he repaired what had been broken. The contest on Mount Carmel was about whether Yahweh or Baal would answer by fire, but it began with restoring the altar. Revival in Scripture is often portrayed as a return to the altar, a rebuilding of what neglect and false worship had destroyed. That is a sobering picture of what drift looks like over time.
Repeatedly in Israel's history, faithful kings are described as removing high places and destructive kings as multiplying altars to false gods. The altar was never neutral ground. An altar to Yahweh and an altar to Baal could look similar, but they represented utterly different loyalties. This is why the prophets are so sharp about worship that is outwardly correct but morally corrupt. Amos condemns those who bring offerings while oppressing the poor. The altar does not cover injustice; it exposes whether our worship is genuine. Sacrifice without obedience is an insult, not a gift.
This history should make us ask about the altars in our own lives. Not literal altars, but the places we return to for meaning, comfort, and identity. Everyone has an altar in that sense, a functional center of trust and sacrifice. The Bible's demand is exclusive: the altar belongs to Yahweh, and he will not share it. When Israel tried to keep both, disaster followed. The same is true for us. The gospel calls us to tear down every rival altar and to come to the one sacrifice God has provided, trusting nothing and no one else for acceptance before him.
The altar, the gift, and the brother at odds with you
Matthew 5:23-24 says, If therefore you are offering your gift at the altar, and there remember that your brother has anything against you, then leave your gift there before the altar and go your way. First be reconciled to your brother, and then come and offer your gift. Jesus assumes the altar as the place of worship and speaks to the worshipper approaching it. His point is not that sacrifice is unimportant; it is that God does not separate worship from relationships. A gift offered at the altar while a wrong remains unaddressed is not acceptable worship.
This is a striking reversal of business as usual. We tend to think the ritual is the urgent thing, and reconciliation can wait. Jesus says the opposite. Leave the gift; go first. The altar does not buy us permission to neglect people. If anything, it exposes our need to make peace. The altar is a place of humility before God, and humility before God necessarily expresses itself in humility before others. That is why Jesus ties forgiveness so tightly to prayer in the Lord's Prayer and why he tells parables about unforgiving servants.
Practically, this means we should not use worship as a hiding place. Singing, listening to preaching, and giving can all become masks that cover unresolved conflict. The altar message is unsettling, but it is kind. It says, deal with your brother. Not every conflict is your fault, and reconciliation is not always possible because it takes two willing parties. Scripture acknowledges that as far as it depends on you, you are to live at peace with everyone. But where you can make peace, the altar is no excuse to delay. Go first. The worship will be truer when you return.
And notice the reason given: your brother has anything against you. The offence may have been unacknowledged on your side. It takes real humility to ask whether someone has something against us rather than waiting for them to approach us. The altar of earth, with its lowly material and its lack of ornamentation, is a fitting place for that kind of honesty. We come with nothing to boast about. If we truly grasp that we approach God only by mercy, we will find it easier to seek mercy from those we have wronged and to extend mercy to those who have wronged us.
Our altar: what Hebrews says about the sacrifice that ends sacrifice
Hebrews 13:10 says, We have an altar from which those who serve the holy tabernacle have no right to eat. This is one of the most important New Testament statements about the altar theme. It does not describe a physical structure. It points to Christ and his once-for-all sacrifice, which the old system could only shadow. Those who continue to serve the tabernacle by relying on its sacrifices cannot share in this altar, because the altar is Christ himself. To eat from it is to receive him by faith and to be nourished by his finished work.
This confirms what the rest of Hebrews argues: the sacrifices of the law could never take away sins, and they were repeated because they were incomplete. Christ offered one sacrifice for sins forever and sat down, because the work was finished. There is therefore no remaining sacrifice to be offered on an altar in the Old Testament sense. Any teaching that repeats the sacrifice of Christ, whether by claiming to re-present it or by telling us we must add our own suffering to complete it, contradicts the book of Hebrews. The altar of the New Covenant is a finished altar, and its sacrifice is not repeated.
At the same time, Hebrews has a warning. If the altar is Christ and those who reject him have no right to eat, then there are only two options. Either we come to him, or we remain outside. The altar is not an optional add-on to a generally religious life. It is the crossroads. Revelation 6:9-10 deepens the picture: When he opened the fifth seal, I saw underneath the altar the souls of those who had been killed for the Word of God, and for the testimony of the Lamb which they had. The heavenly altar is associated with the sacrifice of the faithful, and God will avenge them in his time.
This is a sober and hopeful picture. The altar underscores that worship involves cost, that faithfulness may lead to suffering, and that God does not forget. The souls under the altar cry out, and they are told to rest until the full number is complete. The altar of Scripture is a place of sacrifice, meeting, and ultimately vindication. We come to it now through Christ, with the promise of blessing and the call to bear our own cross. The altar is not a relic of an outdated religion; it is a lens for understanding the whole story of redemption, from Noah to the cross to the throne room of heaven.
How to read altar passages without superstition or overreach
When reading altar passages, first ask who commanded the altar and what sacrifice was offered. In Exodus 20:24-26 God himself gives the specifications, so the altar is legitimate. Where people build altars without God's direction, or to other gods, Scripture treats it as rebellion. The question is never merely whether an altar exists, but whether it is Yahweh's altar and whether the sacrifice is the one he appointed. That is why the book of Kings constantly evaluates rulers by whether the high places remained. Structure alone does not please God.
Second, note that the altar was always a means, not an end. God says, In every place where I record my name I will come to you and I will bless you. The altar is the place where his name is remembered, and the blessing is his presence. Where the structure is honored but his name is forgotten, the altar becomes an idol. Jeremiah and Amos both condemn worship that continues at the altar while the worshippers live like the surrounding nations. God is not served by ritual performed as a substitute for obedience.
Third, read every Old Testament altar in light of Christ. The sacrifices pointed forward to a greater sacrifice. When Jesus said he would replace the temple, he was not abolishing the altar theme; he was fulfilling it. Hebrews tells us we have an altar, and it is not made of earth or stone. If we read the Old Testament altars without seeing this, we either try to rebuild them, which the New Testament does not command, or we dismiss them entirely, which loses the richness of the story. The two errors are opposite, and both miss the point.
Finally, let the altar search your heart. The Bible's altars reveal what people trusted and what they were willing to give. Ask what you look to when you need help, comfort, or identity, and whether that is the one altar God has provided. The sacrifices of God, Psalm 51 says, are a broken spirit, and the psalmist knows that such a heart is the sacrifice God will not despise. Not because our sorrow earns anything, but because it is the honest posture of people who come to him on his terms. That is what an altar is for.
Biblical fidelity check
What Exodus 20:24-26 does establish is clear. It commands Israel to build an altar of earth and to sacrifice burnt offerings and peace offerings on it, and it attaches a promise of God's presence and blessing wherever his name is recorded. It also gives the altar's defining purpose: sacrifice on it. The passage does not establish that all altars everywhere are valid, nor that physical objects convey God's presence, nor that New Testament believers are commanded to construct altars for sacrifice. The promise is tied to God's name and God's appointed worship, not to the structure itself. Anyone may build a pile of stones, but only God can promise to meet his people there.
A common misreading is to treat the altar as a kind of spiritual technology, as if the right object, location, or ritual guarantees a divine response. That is exactly the superstition Israel later fell into with the ark and the temple, and the prophets rebuked it. Another misreading is to assume the New Testament abolishes the altar, when Hebrews 13:10 speaks of our altar as Christ himself and Revelation 6:9-10 pictures a heavenly altar. The correct reading keeps both: the old altars were provisional and pointed forward, and Christ is the once-for-all sacrifice who ends the need for further altars of that kind. Where faithful Christians differ, they differ mainly on how to apply altar imagery to church practice, not on the sufficiency of Christ's sacrifice. On that, Scripture is plain and we should be too.
Other passages that speak to Exodus 20:24-26
Several related studies help place this passage in its wider biblical context. If you want to see how God reveals himself through ordinary created things, and how that differs from the altar's special revelation, read Natural revelation and what creation reveals about God: A Biblical Guide. To understand the earliest altar in Scripture and the world it was built in, see What Genesis Actually Says About the Ark. For the nature of faith that brings a person to the altar and holds on to God's promise, What does Hebrews 11:1 mean by faith? is a helpful study. And because the altar calls people to come to God for rest rather than to earn his favor, consider What does Matthew 11:28-30 mean by easy yoke?.
Frequently asked questions
Does the Bible still require Christians to build altars today?
The New Testament never commands believers to build physical altars for sacrifice. The old altar system was fulfilled in Christ, who offered himself once for all. Hebrews 13:10 points to him as our altar. What remains is not a structure but a life of worship, offered through him. We bring our bodies as living sacrifices, we thank God, and we do good, which Hebrews calls sacrifices pleasing to God. Building a stone or earth altar would not add anything to Christ's finished work. The altar theme now directs us to him rather than to a place.
Why did God ask for an altar of earth and uncut stones?
An altar of earth was humble, available to everyone, and impossible to turn into a boast. Uncut stones served the same purpose: no human craftsmanship could compete with the sacrifice or become an object of pride. Surrounding nations built elaborate platforms and decorated shrines, and God deliberately chose simplicity so his people would not imitate them or imagine their own skill secured his favor. The plain altar teaches that God accepts worship on his terms, by his provision, not because of what the worshipper builds. It is a quiet sermon about grace.
What did Jesus mean when he told the man to leave his gift at the altar?
In Matthew 5:23-24 Jesus teaches that worship and reconciliation cannot be separated. If you are offering your gift and remember that your brother has something against you, leave the gift and go make peace first. He is not dismissing the offering; he is saying that God will not accept worship that ignores broken relationships. The altar is a place of humility, and humility before God must show itself in how we treat others. Where reconciliation is genuinely impossible, we still do what we can, but we should never use worship as a cover for unresolved wrongs.
