Here is, I. The general establishment of God's covenant with this new world, and the extent of that covenant, Gen 9:9, Gen 9:10. Here observe, 1. That God is graciously pleased to deal with man in the way of a covenant, wherein God greatly magnifies his condescending favour, and greatly encourages man's duty and obedience, as a reasonable and gainful service. 2. That all God's covenants with man are of his own making: I, behold, I. It is thus expressed both to raise our admiration - "Behold, and wonder, that though God be high yet he has this respect to man," and to confirm our assurances of the validity of the covenant - "Behold and see, I make it; I that am faithful and able to make it good." 3. That God's covenants are established more firmly than the pillars of heaven or the foundations of the earth, and cannot be disannulled. 4. That God's covenants are made with the covenanters and with their seed; the promise is to them and their children. 5. That those may be taken into covenant with God, and receive the benefits of it, who yet are not capable of restipulating, or giving their own consent. For this covenant is made with every living creature, every beast of the earth.

II.The particular intention of this covenant. It was designed to secure the world from another deluge: There shall not any more be a flood. God had drowned the world once, and still it was as filthy and provoking as ever, and God foresaw the wickedness of it, and yet promised he would never drown it any more; for he deals not with us according to our sins. It is owing to God's goodness and faithfulness, not to any reformation of the world, that it has not often been deluged and that it is not deluged now. As the old world was ruined to be a monument of justice, so this world remains to this day, a monument of mercy, according to the oath of God, that the waters of Noah should no more return to cover the earth, Isa 54:9. This promise of God keeps the sea and clouds in their decreed place, and sets them gates and bars; hitherto they shall come, Job 38:10, Job 38:11. If the sea should flow but for a few days, as it does twice every day for a few hours, what desolation would it make! And how destructive would the clouds be, if such showers as we have sometimes seen were continued long! But God, by flowing seas and sweeping rains, shows what he could do in wrath; and yet, by preserving the earth from being deluged between both, shows what he can do in mercy and will do in truth. Let us give him the glory of his mercy in promising and of his truth in performing. This promise does not hinder, 1. But that God may bring other wasting judgments upon mankind; for, though he has here bound himself not to use this arrow any more, yet he has other arrows in his quiver. 2. Nor but that he may destroy particular places and countries by the inundations of the sea or rivers. 3. Nor will the destruction of the world at the last day by fire be any breach of his promise. Sin which drowned the old world will burn this.

Whoso sheddeth man's blood, by man shall his blood - Hence it appears that whoever kills a man, unless unwittingly, as the Scripture expresses it, shall forfeit his own life.

A man is accused of the crime of murder; of this crime he is guilty or he is not: if he be guilty of murder he should die; if not, let him be punished according to the demerit of his crime; but for no offense but murder should he lose his life. Taking away the life of another is the highest offense that can be committed against the individual, and against society; and the highest punishment that a man can suffer for such a crime is the loss of his own life. As punishment should be ever proportioned to crimes, so the highest punishment due to the highest crime should not be inflicted for a minor offense. The law of God and the eternal dictates of reason say, that if a man kill another, the loss of his own life is at once the highest penalty he can pay, and an equivalent for his offense as far as civil society is concerned. If the death of the murderer be the highest penalty he can pay for the murder he has committed, then the infliction of this punishment for any minor offense is injustice and cruelty; and serves only to confound the claims of justice, the different degrees of moral turpitude and vice, and to render the profligate desperate: hence the adage so frequent among almost every order of delinquents, "It is as good to be hanged for a sheep as a lamb;" which at once marks their desperation, and the injustice of those penal laws which inflict the highest punishment for almost every species of crime. When shall a wise and judicious legislature see the absurdity and injustice of inflicting the punishment of death for stealing a sheep or a horse, forging a twenty shillings' note, and Murdering A Man; when the latter, in its moral turpitude and ruinous consequences, infinitely exceeds the others?* (* On this head the doctor's pious wish has been realized since this paragraph was written. - Publishers)

And I will establish my covenant with you,.... This is repeated to denote the certainty of it, as well as to lead on to the particulars of it:

neither shall all flesh be cut off any more by the waters of a flood; neither man nor beast, at least not all of them, and especially by water:

neither shall there be any more a flood to destroy the earth; not a general deluge, otherwise notwithstanding this promise there might be, as there have been, particular inundations, which have overflowed particular countries and places, but not the whole earth; and this hinders not but that the whole earth may be destroyed by fire, as it will be at the last day, only not by water any more; and this is the sum and substance of the covenant with Noah, his sons, and all the creatures that have been, or shall be.

Whoso sheddeth man's blood . . . for in the image of God made he man--It is true that image has been injured by the fall, but it is not lost. In this view, a high value is attached to the life of every man, even the poorest and humblest, and an awful criminality is involved in the destruction of it.
