If we attend to the phraseology of this decree of God, we shall find it to be very different from that of the precepts, generally, delivered to Moses. God did not say to Noah, as he often did to Moses, thou shalt do this, or that, but he said, "_I will require the life of man_," etc. If God had designed to delegate executive authority to Noah and his descendants to execute retributive judgment on the manslayer, the connection of the whole language must have been altered, for God declared what he would do himself. It appears, therefore, to have been God's _decree_, and the promulgation of _his_ law by which he would inflict righteous judgment on the guilty; the penalty was intended as a warning to deter mankind from violence, the sin for which the old world was swept away. And I see no reason why this threatening should not be considered parallel with the decrees of Christ,--that "all they that take the sword shall perish with the sword; he that leadeth into captivity shall go into captivity; he that killeth with the sword must be killed with the sword; here is the faith and the patience of the saints." Why the former should be considered as a rule of obedience for man, and these latter passages not so, I am unable to say. "He that killeth with the sword must be killed with the sword" is as positive as "whoso sheddeth man's blood, by man shall his blood be shed." It may be observed that the faith and patience of the saints is here spoken of in such a way as to imply that they exercised and manifested their faith and patience when they were put to death by violence or carried into captivity. And, indeed, how could their faith and patience appear if they, like the wicked world, returned evil for evil, carried into captivity, and killed with the sword? The original threatening has been fulfilled by the providence, and sometimes by the express command, of God. As Noah was the head of the new world and the father of nations, it seems to have had reference to nations rather than to individuals; and all nations that have shed blood in war must, in their turn, have their own blood shed; so that all they that take the sword may perish with the sword agreeably to the threatening made known to Noah, and to those announced by Christ. But, admitting that the law quoted in the objection was intended as a rule of duty for man, it does not appear that it was designed to be universal and perpetual. Before the flood no authority appears in any sense to have been delegated to man to shed the blood of man. So far from executing the penalty of death or causing it to be executed upon Cain, who was of the wicked one and slew his brother, notwithstanding his guilty forebodings, God threatened a sevenfold vengeance on him who should presume to do it.
