Question: "Why is "You shall not murder" in the Ten Commandments?"
Answer: Simply stated, the sixth of the Ten Commandments forbids the unjustified taking of a human life. However, the commandment itself has a couple of interesting elements that bear mentioning. First and foremost, different Bible translations give the appearance of different meanings, and there is potential for misunderstanding the actual meaning of the verse. Second, man was never created for the act of murdering another, and there needs to be an explanation for such a violent and final act towards another human being. Third, because of the translational challenge, we need to understand the difference between “murder” and “killing.” And last but not least, how does God view murder? To God, murder is not just physical in nature but also the condition of one’s heart towards another.
There are two different Hebrew words (ratsakh, mut) and two Greek words (phoneuo, apokteino) for “murder” and “killing.” One means “to put to death,” and the other means “to murder.” The latter one is the one prohibited by the Ten Commandments, not the former. In fact, ratsakh has a broader definition than the English word “murder.” Ratsakh also covers deaths due to carelessness or neglect but is never used when describing killing during wartime. That is why most modern translations render the sixth commandment “You shall not murder” rather than “You shall not kill.” However, a very large issue can arise depending on which translation one studies. The ever-popular King James Version renders the verse as “Thou shalt not kill,” therefore opening the door to misinterpreting the verse altogether. If the intended meaning of “Thou shalt not kill” was just that—no killing—it would render all of the God-endorsed bloodletting done by the nation of Israel a violation of God’s own commandment (Deuteronomy 20). But God does not break His own commandments, so, clearly, the verse does not call for a complete moratorium on the taking of another human life.
Why does man murder? We know that we were created in God’s image (Genesis 1:27) and we were made to live in harmony with God and with our fellow man. This harmony became impossible once sin entered into the picture (Genesis 3). With sin came the propensity for acting violently against one another. Anger, jealousy, pride and hatred can fuel man’s evil bent towards life-ending aggression. The first recorded act of murder was when Cain killed his brother Abel (Genesis 4:8). From that moment on, taking the life of another has been commonplace and, in some circles of society, acceptable. However, to God every life is important, and since God knew that man was sinful and evil and had become “lawless,” He enacted guidelines that would seek to modify man’s behavior (1 John 3:4).
So, is there a difference between murder and killing? First, it is important to note that not all killing is wrong. For instance, the apostle Paul talks about the right of the state to take the lives of evildoers (Romans 13:1-7). This relates to what is commonly referred to as capital punishment. Most countries have consequences for murder. In some cases this requires the life of the perpetrator and a suitable means of putting one to death is chosen and administered (Matthew 5:21; Exodus 21:14). Another instance of acceptable “killing” is that which is done during times of war and at the command of superiors. There were quite a few instances in Scripture where God endorsed and allowed the taking of other lives (1 Samuel 11; Judges 6–7). And finally, although far from acceptable, manslaughter is yet another form of killing someone. This unintentional act apparently happened so often in biblical times that cities of refuge were designated for the manslayer to seek refuge in (Exodus 21:13; Joshua 20). Again, it was never God’s intent to have to use such a drastic measure as taking one’s life to rectify a situation. So, God does make exceptions for the taking of another’s life as long as it lines up with His will. However, premeditated murder of an individual is never God’s will.
What is murder in God’s eyes? From the human perspective, murder is the physical act of taking another’s life. However, we also must consider that God defines murder as any thought or feeling of deep-seated hatred or malice against another person. In other words, it is more than just a physical act that constitutes murder to God, who tells us that “everyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him” (1 John 3:15 ESV). When we harbor hatred in our hearts for another, we have committed the sin of murder in God’s eyes. The disdain towards another person never has to be demonstrated outwardly because God looks upon the heart for the truth (1 Samuel 16:7; Matthew 15:19). As Christians and as human beings, we know that unjustified killing is wrong. God’s Word is very clear on this point: “You shall not murder.” And what God says we must obey, or we face the consequences on judgment day.
