Genesis 9:6

Gen. 1:27 Matt. 26:52 ; Rev. 13:10 Not only by the magistrate, but oft times God raiseth up one murderer to kill another. Therefore to kill man is to deface God’s image, and so injury is not only done to man, but also to God.

Shed. God had not subjected Cain to this law of retaliation, as he was the first murderer, and the earth was unpeopled. (Haydock) — Here he declares, that it is just to inflict such a punishment on the offender. (Menochius) — Judges are hence authorized to punish murderers with death. (Calmet) — The general law, thou shalt not kill, admits of exceptions, and forbids killing by private authority, or out of revenge. (Haydock) — The blood of your lives, may signify the blood on which your life depends; or, according to the Rabbin, it is a prohibition of suicide, which one would think is so contrary to the first law of nature, self-preservation, as to require no prohibition; and yet, to the scandal of philosophers, some have written in its defence! (Haydock)

4. Wilful murderers must be put to death. This is the sin which is here designed to be restrained by the terror of punishment (1.) God will punish murderers: At the hand of every man's brother will I require the life of man, that is, "I will avenge the blood of the murdered upon the murderer." 2 Chron 24 22. When God requires the life of a man at the hand of him that took it away unjustly, the murderer cannot render that, and therefore must render his own in lieu of it, which is the only way left of making restitution. Note, The righteous God will certainly make inquisition for blood, though men cannot or do not. One time or other, in this world or in the next, he will both discover concealed murders, which are hidden from man's eye, and punish avowed and justified murders, which are too great for man's hand. (2.) The magistrate must punish murderers (v. 6): Whoso sheddeth man's blood, whether upon a sudden provocation or having premeditated it (for rash anger is heart-murder as well as malice prepense, Matt 5 21, 22), by man shall his blood be shed, that is, by the magistrate, or whoever is appointed or allowed to be the avenger of blood. There are those who are ministers of God for this purpose, to be a protection to the innocent, by being a terror to the malicious and evildoers, and they must not bear the sword in vain, Rom 13 4. Before the flood, as it should seem by the story of Cain, God took the punishment of murder into his own hands; but now he committed this judgment to men, to masters of families at first, and afterwards to the heads of countries, who ought to be faithful to the trust reposed in them. Note, Wilful murder ought always to be punished with death. It is a sin which the Lord would not pardon in a prince (2 Kings 24 3, 4), and which therefore a prince should not pardon in a subject. To this law there is a reason annexed: For in the image of God made he man at first. Man is a creature dear to his Creator, and therefore ought to be so to us. God put honour upon him, let not us then put contempt upon him. Such remains of God's image are still even upon fallen man as that he who unjustly kills a man defaces the image of God and does dishonour to him. When God allowed men to kill their beasts, yet he forbade them to kill their slaves; for these are of a much more noble and excellent nature, not only God's creatures, but his image, Jam 3 9. All men have something of the image of God upon them; but magistrates have, besides, the image of his power, and the saints the image of his holiness, and therefore those who shed the blood of princes or saints incur a double guilt.

Verses 4-7 The main reason of forbidding the eating of blood, doubtless was because the shedding of blood in sacrifices was to keep the worshippers in mind of the great atonement; yet it seems intended also to check cruelty, lest men, being used to shed and feed upon the blood of animals, should grow unfeeling to them, and be less shocked at the idea of shedding human blood. Man must not take away his own life. Our lives are God's, and we must only give them up when he pleases. If we in any way hasten our own death, we are accountable to God for it. When God requires the life of a man from him that took it away unjustly, the murderer cannot render that, and therefore must render his own instead. One time or other, in this world or in the next, God will discover murders, and punish those murders which are beyond man's power to punish. But there are those who are ministers of God to protect the innocent, by being a terror to evil-doers, and they must not bear the sword in vain, ( Romans 13:4 ) . Wilful murder ought always to be punished with death. To this law there is a reason added. Such remains of God's image are still upon fallen man, that he who unjustly kills a man, defaces the image of God, and does dishonour to him.
