Exodus 20:13 Meaning: Why God Says You Shall Not Murder
Short answer: Exodus 20:13 says, "You shall not murder." The command forbids the unlawful, deliberate taking of a human life, and its foundation is that people are made in God's image. It is not a blanket statement about every death; the same Bible that gives this command prescribes capital punishment for murder (Genesis 9:6) and authorises governing authorities to wield the sword (Romans 13:1-4). Jesus did not cancel the command but deepened it, tracing murder back to anger and contempt in the heart (Matthew 5:21-22). The apostle John goes further still, writing that whoever hates his brother is a murderer (1 John 3:15). So the sixth commandment is both a limit on what we may do to a body and a mirror held up to the heart.
What the Hebrew word in Exodus 20:13 actually means
The command in Exodus 20:13 reads, "You shall not murder." The Hebrew verb behind that word is ratsach, and its range matters enormously for how the commandment is applied. It is not the ordinary verb for killing in general. It is the verb used elsewhere in the law for the man who lies in wait and strikes down his neighbour, for the slayer who must flee to a city of refuge, and for blood unlawfully shed. The command addresses the unauthorised, culpable taking of life. That is why the same law code can condemn murder and still prescribe death for certain crimes without contradicting itself.
This distinction is not a modern escape hatch. It is built into the text. If ratsach simply meant any causation of death, then the instructions that follow in Exodus 21 would be self-contradictory, since they impose death on a kidnapper and on a man who strikes his father or mother. The commandment is a prohibition of murder, not of justice, not of war, and not of every tragic death. Reading the word carefully keeps us from either softening the command into vague niceness or stretching it into a rule the Bible itself never made.
Notice also the form. It is short, absolute, and addressed to the whole covenant community: you, singular, shall not murder. It is not given only to judges or kings. Every Israelite is bound. The brevity is deliberate; there is no exception clause attached, because the exceptions are defined elsewhere in the law, not in the commandment itself. The command sets the default: human life is not yours to take. Any taking of life must be justified by God's own word, not by our convenience or anger.
Because the command is so short, it is easy to flatten it into a slogan and then use it for whatever cause we already favoured. The better path is to let the wider law explain the word, and then let the New Testament show how the command reaches the heart. What we find is a command that is narrower than total pacifism in its wording and far deeper than mere external restraint in its intent. It protects the innocent and it exposes the murderer, and it does not stop at the hand.
Made in God's image: the reason murder is so serious
Genesis 9:6 gives the reason the commandment carries such weight: "Whoever sheds man's blood, his blood will be shed by man, for God made man in his own image." The ground of the prohibition is not that human beings are useful, or rare, or sentient, or loved by their families. It is that they bear the image of God. That is what makes murder a crime against God before it is a crime against a person. To destroy an image is to insult the one whose image it is.
This is why the Bible treats murder as a peculiar category of wrongdoing. Other sins are serious, but bloodshed has a voice. After Cain killed Abel, God said that Abel's blood cried out from the ground. The psalmist describes blood as crying out for justice. The book of Revelation pictures the souls of the slain calling for judgement. Human life is not merely biological; it is representative. Every person stands in the world as a visible sign of the God who made them, and murder is an assault on that sign.
The image of God also explains why murder cannot be atoned for by an ordinary payment. In Israel's law, no ransom could be accepted for the life of a murderer. The offence was too great. This is not bloodthirstiness; it is a sober assessment of what a human being is. If you take a life, you have destroyed something that cannot be replaced, and the only just response the law knows is the forfeiture of your own. That is the logic behind Genesis 9:6, and it is why the commandment is placed among the ten words rather than in a list of case laws.
For the Christian, the image of God is also the reason we speak of the dignity of every person, born and unborn, strong and weak, useful and inconvenient. The command does not protect only the lives we value. It protects the lives God made. That includes the elderly, the disabled, the stranger, the enemy, and the person whose existence is inconvenient to us. The image is not earned by capacity or contribution. It is conferred by the Creator, and no human court or committee can revoke it.
What the sixth commandment does and does not prohibit
Because the commandment forbids murder, it does not forbid everything that ends a human life. The same law that says, "You shall not murder," also commands the death penalty for murder, and Romans 13:1-4 describes the governing authority as a servant of God who does not bear the sword in vain. Scripture also records wars commanded by God, and it distinguishes between the man who kills unintentionally and the man who lies in wait. These distinctions are not embarrassments to the commandment; they are the commandment's own framework.
This means the honest Christian reader has to do careful work rather than reach for a slogan. Questions about war, policing, self-defence, and capital punishment are not settled by quoting Exodus 20:13 alone, and faithful believers who take the whole Bible seriously have differed on some of them. What the commandment settles is that killing is never trivial and never to be done for private vengeance or gain. The default is protection of life, and any exception must be established from Scripture, not assumed from culture or convenience.
The commandment also does not prohibit the ordinary ending of life in the course of a fallen world. People die of disease and age. The Bible does not treat death itself as murder, because death is the common enemy (1 Corinthians 15:26). What the commandment addresses is the moral act of a creature taking another creature's life without warrant. That is a crucial difference; confusing death with murder makes the commandment say more than it says and can burden grieving families with a false guilt the Bible never imposes.
At the same time, the narrowness of the word must not become a loophole. We cannot say, I did not technically murder, and therefore I am clean. The law of God reaches intentions, and Jesus will make that explicit in the Sermon on the Mount. The command against murder is a floor, not a ceiling. It tells us the minimum, and then it invites us to see the heart behind the minimum. The person who reads it only as a rule about corpses has not yet heard it.
Jesus and the heart: Matthew 5:21-22
In Matthew 5:21-22, Jesus says, "You have heard that it was said to the ancient ones, 'You shall not murder;' and 'Whoever murders will be in danger of the judgment.'" He does not stop there. He goes on to warn that anger and contempt bring a person into the same danger. This is not a new commandment replacing an old one; it is the true meaning of the old one, spoken by the one who gave it. The sixth commandment was never only about the hand.
Jesus traces murder to its root. Anger that broods, insults that diminish a person, the settled contempt that treats another human being as beneath us; these are the raw materials of murder. Where they are allowed to grow unchecked, the act is only a matter of opportunity. That is why Jesus says the heart is the real battleground. He is not saying that thinking angry thoughts is identical to killing someone, but he is saying they belong to the same family, and the family is condemned by the commandment.
This teaching does not make the external act unimportant. Jesus is not spiritualising the command into nothing. He is exposing the hypocrisy of a person who never lifts a hand but nurses a heart full of hatred. Such a person may keep the law's letter and break its spirit. The Sermon on the Mount consistently does this: it drives us past the surface and shows us that our problem is not merely what we do but what we are. That is a humbling message for every reader, not just for obvious sinners.
The application is intensely practical. It means that gossip, slander, mockery, and the slow cultivation of bitterness are not minor matters. It means that when we are angry, we are on the same road as the murderer, and we need to turn off it quickly. It means that reconciliation is not optional for the Christian; Jesus ties it directly to worship. If we are serious about the sixth commandment, we cannot be casual about the way we speak to and about other people, especially those closest to us.
Hatred is murder: 1 John 3:15 and the Christian's life
1 John 3:15 says, "Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him." This is a startling sentence, and it is meant to be. John is not adding a new law; he is drawing out the implications of Jesus' teaching in a pastoral letter written to a church tempted to divide. The man who hates his brother is already, in God's sight, a murderer. The act may not have happened, but the heart has already gone there.
John's argument is about the evidence of eternal life. He is not saying that a believer who struggles with anger has lost salvation. He is saying that a settled, unrepentant hatred is incompatible with the life of God. The two cannot coexist, any more than light and darkness can. His point is pastoral and searching: if you claim to love God and you hate your brother, you are deceiving yourself. The test is not only whether you have avoided murder but whether you love the people God has placed around you.
This is where the sixth commandment touches the ordinary Christian life. It confronts the feud we will not end, the family member we will not forgive, the brother or sister in the church we have written off. It confronts the way we talk about people we disagree with, and the contempt that colours our politics and our disputes. John does not allow us to file these away as personality differences. He names them for what they are. Hatred is murder in seed form, and the seed produces a harvest.
But John's letter is also full of hope. The same author who says hatred is murder also says that if we confess our sins, God is faithful and just to forgive us. The command does not exist to drive us to despair; it exists to drive us to Christ. The one who kept the sixth commandment perfectly, and who died for those who broke it, offers cleansing and a new heart. The Christian is not called to manage hatred but to have it put to death by the Spirit, and to replace it with love that acts.
Cain, the city of refuge, and the mercy that surrounds the law
It is worth remembering that the sixth commandment does not stand alone in a harsh wilderness. The law of Moses is surrounded by provisions of mercy. The cities of refuge existed so that a man who killed someone unintentionally could flee and be protected from the avenger of blood. A distinction was made between premeditated murder and accidental death. Even the command against murder was accompanied by care for the person who had killed without intent. God's law is not bloodthirsty; it is careful.
Cain is the first murderer, and his story is instructive. God confronted him, and Cain's answer was insolent: he claimed he did not know where Abel was. Yet even then, God did not immediately execute Cain. He put a mark on him and protected him from being killed by others. This does not mean God treated the murder lightly; it means that from the beginning, God reserved the taking of life to himself and to the authorities he would later establish. Vengeance was not Cain's neighbours' to take.
That pattern continues in Israel's law. The avenger of blood is regulated. The cities of refuge are appointed. The accidental killer is sheltered. The deliberate murderer is handed over. There is a system, not a vendetta. The sixth commandment fits into a legal order that is meant to restrain violence rather than multiply it. It is a gift to a violent world, not a burden imposed on peaceful people. It says: stop, and let justice be done in its proper place.
For the modern reader, this is a reminder that laws against murder exist because God established them and because human societies cannot flourish without them. When we honour the sixth commandment, we honour the whole structure of order that God has built around human life. We also honour the mercy woven into that structure for those who have not murdered but have been involved in death by misfortune. The law protects the innocent and provides for the guilty; it is the expression of a God who is both just and merciful.
Revelation 21:8 and the seriousness of the command
Revelation 21:8 lists murderers among those whose part is in the lake of fire, the second death. The list is sobering and it is broad: the cowardly, unbelieving, sinners, abominable, murderers, the sexually immoral, sorcerers, idolaters, and all liars. Murder is not a small matter in the Bible's final book. It is mentioned alongside the sins that mark an unconverted life. The command that begins as an instruction to the covenant community ends in the warning of final judgement for those who persist in breaking it.
This should not make us morbid, but it should make us honest. The Bible teaches that God will judge the world in righteousness, and that no sin is trivial. The sixth commandment protects human life because God values it, and those who despise that value will answer to God. The warning is not given to create panic among believers, but to make clear that murder belongs to the old creation that will not inherit the new. The murderers in Revelation 21:8 are those who remain murderers, whose lives are characterised by it and whose hearts are never changed.
At the same time, the context of Revelation 21 is not merely judgement but the promise of a new creation where death itself is finally undone. The New Testament looks forward to the resurrection of the body and the destruction of the last enemy. The command against murder is provisional; it protects life in a world where death is real. In the world to come, there will be no more threat, no more violence, and no more grief over the slain. The command is the interim guardrail on a road that ends in life without end for those who belong to Christ.
So the sixth commandment is both a warning and a signpost. It warns us of the seriousness of taking life and of the hatred that leads there. It points us toward the God who gave it, the God who made us in his image, and the God who offers forgiveness to anyone who turns from sin to his Son. The command does not stand alone; it stands within the whole counsel of God, which ends not in the lake of fire for those who repent, but in a city where no one will be hurt any more.
Biblical fidelity check
What Exodus 20:13 establishes is this: the deliberate, unlawful taking of a human life is forbidden, because human beings are made in the image of God, and the penalty for that sin is severe. It does not establish that all killing is forbidden in every circumstance, because the same Scriptures that give the command also authorise the sword of the governing authority and prescribe capital punishment for murder. It does not establish that accidental death is murder, because the law distinguishes intentional killing from the unintentional. It does not establish that the command is confined to the external act, because Jesus and John both extend it to anger and hatred in the heart.
A common misreading is to treat Exodus 20:13 as a proof text for total pacifism. That reading imports a modern assumption into the Hebrew word. If ratsach forbade every causing of death, the laws immediately following in Exodus 21 and the institution of capital punishment throughout the Pentateuch would contradict it. Another misreading is the opposite: to treat the command as merely external, so that anger and contempt are harmless. Jesus explicitly rejects that in Matthew 5:21-22, and John says hatred is murder in 1 John 3:15. The faithful reading holds both: the act is forbidden, and the heart that produces it is condemned.
Other passages that speak to Exodus 20:13
If you want to trace how the Bible handles death, resurrection, and the final answer to murder, these studies continue the theme: 1 Corinthians 15:20-28: Resurrection Order and the Final Defeat of Death, where the last enemy is destroyed; What Does 1 John 1:1 Mean? Context, Theology, and Application, which grounds the apostle's testimony about life; What Does 1 John 1:8 Mean? Context, Theology, and Application, which explains why we must not deny our sin; and 1 John 1:9 Meaning: Confession, Forgiveness, and Cleansing, which shows the way back for those who have broken God's commands.
Frequently asked questions
Does Exodus 20:13 forbid all killing, including war and capital punishment?
The Hebrew verb is ratsach, which refers to unlawful, culpable killing rather than every causing of death. The same law code that contains the command also prescribes capital punishment for murder and regulates warfare. Romans 13:1-4 describes the governing authority as God's servant who bears the sword. So the commandment forbids murder, not every act that ends a life. Christians have differed over how far these exceptions extend, but the word itself does not support a blanket prohibition of all killing in every circumstance.
Why does Jesus connect anger with murder in Matthew 5:21-22?
Jesus is not adding a new rule; he is revealing the root of the old one. Murder does not begin in the hand but in the heart, in brooding anger and contempt that treats another person as worthless. By naming anger and insult, Jesus shows that the sixth commandment addresses the whole person, not just the external act. The person who never strikes but hates is still on the same road. This teaching calls for repentance at the level of the heart and makes reconciliation a serious Christian duty.
Can a murderer be forgiven and saved?
Yes. Scripture is clear that no sin is beyond the reach of Christ's atonement. The apostle Paul, who described himself as a blasphemer and persecutor, was shown mercy and became an apostle. Jesus died for sinners, including murderers, and 1 John 1:9 promises forgiveness to those who confess. What 1 John 3:15 and Revelation 21:8 warn against is a settled, unrepentant life of hatred and violence. The person who turns to Christ in repentance is welcomed, cleansed, and given new life.
