Why is "You shall not murder" in the Ten Commandments?

The sixth commandment, "You shall not murder," must be considered from the viewpoint God intends (v.17). Israel had already killed many enemies that God had told them to, and in the land of Canaan would be required to kill the inhabitants. God commanded this because the inhabitants were given up to idol worship. Similarly, when justice demands the death of a criminal, it is not murder for the authorities to put him to death. But no individual is at liberty to kill another as he sees fit. As we have seen before, Scripture makes a distinction between murder and manslaughter (ch.4:41-42).

In the sixth commandment there is the safeguarding of human life, of which God is the Source. Man cannot give life and he has no right to take it away, except he does so as ordained of God. After the flood Noah was authorized to slay animals for food, and government was established and the sword committed to his hand, so that death should be the penalty for murder. In the New Testament we are reminded that the earthly authority "bears not the sword in vain" (Rom. 13:4), which shows that the introduction of grace in Christ has not nullified what has been established as to government in the earth. Authorized government takes its course, but murder is strictly forbidden.

The sixth law, “You shall not kill” finds an echo in everyone's conscience, for he knows this is wrong without being told. Cain, though he had no law, knew he was doing evil in killing his brother, for he lied about it afterward (Gen. 4:8-9).

For this reason God stringently guards human life and death. The very governing authority placed in man's hand would soon be misused and perverted by his will without the fear of God; and rivers of blood would flow, not merely through lawless corruption and violence as before the deluge, but by ambitious kings and governors after it. Therefore does God in His prescient wisdom and considerate goodness declare from the starting point of the new tenure, "Surely your blood [that is] of your lives will I require; at every animal's hand will I require it." Specially of course would He require the life of man at man's hand, even at the hand of each man's brother (Gen. 9:5). And this is set on its sacred and sound principle in Gen. 9:6; By man should his blood be shed who shed man's blood; for in God's image did He make man.

The image of God expresses man's place and responsibility of representing God. Man alone has that image generally, Christ of course specially and alone perfectly and pre-eminently. It is not His likeness; for alas! man lost this by sin and begat in his own likeness, however grace might act as it does by faith to God's glory. But His image, even when fallen as here, man retains; and the man who slays another (save by competent authority) is guilty of denying God's right in this respect; which we see here that God asserts with the utmost plainness, precision, and solemnity. The murderer meddles not merely with man and injures him to the last degree, but he also defaces God's image by killing a man, and God sentences him to die. Murder is unwarrantable assumption of what belongs to God. In no other way but by death of the murderer is God's honour vindicated, and God's will maintained. Men may have decreed otherwise; but they that do so are flying in the face of Him from Whom they derive their own title to govern. For here it is laid down before separate nations began, and before His special legislation for Israel where it was guarded with minute care, and not least in the exceptional case of manslaughter. To Noah was said what binds all mankind since the deluge.

In Genesis 5 we have the generations of Adam. Upon this I would not now dwell farther than to draw attention to the commencing words, "In the day that God created man, in the likeness of God made he him; male and female created he them; and blessed them, and called their name Adam in the day when they were created." But "Adam," it is said, "begat a son in his own likeness, after his image." It was no longer in the likeness of God, but in the image of God always. For man, now as ever, fallen or not, is in the image of God; but the likeness of God was lost through sin. Seth therefore was begotten in Adam's own likeness, not in God's. He was like Adam fallen, not his representative only. And this is what is referred to in James 3, where he speaks of our having been made in the likeness of God. But it is the more important because, when it is a question of the guilt of taking man's life, the ground is that he was made in God's image. This, it is plain, was never lost; it abides, whatever man's state. Had the crime depended on man's retaining the likeness of God, murder might have been denied or justified, because if a man were not like God the unlikeness might be urged in extenuation of killing him. But it is a crime against man made in the image of God, and as this abides, whether he be fallen or not, the guilt of murder is unimpeachable and evident. This accordingly is the ground taken, to which I refer as an instance of the perfectness of scripture, but at the same time of the profound and practical power of the truth of God.

What are we to understand by the words, "image" and "likeness"? Certainly neither term has reference to man's physical frame. Putting it briefly, "image" represents; "likeness" resembles. An image is not necessarily like the thing or person it is intended to represent. The coin that was shown to the Lord Jesus in Matt. 22:20 may not have borne a "likeness" of Caesar, but it certainly bore an "image" of him. As made in the "image" of God, man is set in this world to represent Him to the lower creatures in rule and blessing; this term has thus to do with man's position. "Likeness" has reference to his moral being, as one capable of entering into relationships and bearing responsibilities. Neither God's "image" nor "likeness" has been lost by the fall (Gen. 9:6; James 3:9). It is because of God's image in man that the sin of murder is so serious. To kill one who represents God is high treason against Him whom he represents.

Noah and his sons were blessed and made specially fruitful, so that mankind should multiply rapidly on the renewed earth, and their dominion over the beasts of the earth was emphasized. Moreover man was now given animal food for his sustenance as well as vegetable. And yet further, in the new regime established the sanctity of human life was clearly stated in connection with a primitive form of government. Murder had filled the earth before the flood, and from the time of Cain any human vengeance had been forbidden. But now God would require the blood of man's life at the hand of the slayer, and He would authorize mankind — Noah in particular, no doubt — to be the executor of His judgment. The penalty of death for murder was thus instituted by God Himself, and that from the very start of the post-diluvian age, and not merely as enacted in the law of Moses centuries later. It is of universal validity. Efforts recently made to overturn the Divine enactment are significant, especially if taken in connection with efforts to overturn other basic enactments as to marriage, parental responsibility, etc. The end of the age is marching upon us. It will arrive not with a flood of waters, but in the revelation of the King of kings and Lord of lords, when "He treads the winepress of the fierceness and wrath of Almighty God."

(2) We come now to the second part: here of six commandments. The first claims honor for parents, the earth-type and representatives of the Creator-Father. And to this, as the apostle notes, a special "promise of life"— though but the continuance of it — is attached. The second forbids killing — of course, of men: which our Lord interprets as the prohibition even of anger without cause. It is, as one may say, the salvation-ordinance of the life that is. The third sanctions and sanctifies marriage, and how far it extends the Lord again declares. The fourth has to do with things, not persons, — the goods of others, which it protects from the spoiler. The fifth, under the prohibition of false witness, condemns deceit of every kind, the resource of weakness at all times where God is not before the soul. The numerical place here seems to be intended to remind the creature of his need of God, walking with whom the holiness of truth will be maintained. The sixth and last tracks sin to its lair, discovers it in "lust," as the apostle shows (Rom. 7:7), and shows where victory over it must be found: although the secret of the victory it cannot penetrate. The law is but the "strength of sin" (1 Cor. 15:56), and not of holiness.

(1) The six sins recorded by both Matthew and Mark are the grosser forms of man's evil doings, and, with the exception of blasphemy, which is Godward as well as manward, they relate to the ways in which man does hurt to his neighbour. In the variety of action here specified man shows his habitual breach of the second table of the law, the provisions of which are mainly manward (Matt. 22:39; Mark 12:31). Love is the fulfilling of the law; it thinks no evil, and no harm. Love of one's neighbour therefore secures the observance of the several prohibitions against trespassing upon his rights. The apostle Paul sums up obedience to these particular commandments in this one act. He writes thus to the church at Rome: "For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not covet; and if there be any other commandment it is summed up in this word, namely, Thou shalt love thy neighbour as thyself" (Rom. 13:9). This is the "royal law," which if we fulfil, we shall do well (James 2:8).

The case of murder is first dealt with. This is no new enactment. To Noah God had said, "Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made He man." (Gen. 9:6.) At the hand of every man's brother would He require the life of man. Man therefore was made his brother's keeper, and God protected him whom He had made in His own image by the most solemn penalty which He could exact; for life belongs to Him, and hence he could not suffer another to trench upon His prerogative. Thus when Cain slew his brother Abel, the Lord said unto him, "What hast thou done? The voice of thy brother's blood crieth unto Me from the ground." (Gen. 4:10.) For wilful murder there was no release from the penalty, even though the murderer might have fled for protection to God's altar. (See 1 Kings 2:28-32.) He must die. There is no countenance in the word of God for the modern philanthropic movement for the abolition of capital punishment. It substitutes indeed human ideas in the place of God's primeval law. In fact, it exalts man over God. The directions given by our Lord, in the "sermon on the mount" (Matt. 5:38-48), apply only to the relationships of the fellow-subjects of His kingdom, and not to those existing between man and man, and in no way therefore set aside the precept given to Noah.
