only said to him, Whosoever shall slay thee shall be punished sevenfold. But Adam had such a promise of grace made to him. And Cain, because he was the first-born, ought to have received that promise as an inheritance from his parents. That promise was the large and blessed promise of eternal glory, because by it the seed was promised which should bruise the serpent's head, and this without any work or merit of man. For that promise had no condition attached to it, such as, If thou shalt offer thy sacrifices, if thou shalt do good, etc.
225. If, therefore, you compare this promise of grace with the words God spake to Cain, the latter are as a mere crust held out to a beggar. For even Cain's life is not promised him absolutely. Nothing more is said than a threat pronounced against those who should slay him. God does not say positively, No man shall slay thee. He does not say, I will so overrule all others that no one shall slay thee. Had the words been thus spoken, Cain might have returned into the presence of God and of his parents. But a command only is given to men that they slay not Cain. If, therefore, the words spoken to Cain be at all considered as a promise, it is that kind of promise which, as we have before said, depends on the works and will of man. And yet, even such promise is by no means to be despised, for these legal promises often embrace most important things.
226. Thus, Augustine observes that God gave to the Romans their empire on account of their noble virtues. And in the same manner we find, even to this day, that the blessings of those nations which keep from murder, adultery, theft, etc., are greater than those of other nations in which these evils prevail. And yet, even governments which, as far as mere reason can succeed, are especially well established, possess nothing beyond these temporal promises.
227. The Church, however, possesses the promises of grace, even the eternal promises. And although Cain was left utterly destitute of these promises, yet it was a great favor that the temporal mercies were left him: that he was not immediately killed, that a wife was given him, that children were born unto him, that he built a city, that he cultivated the earth, that he fed his cattle and had possessions, and that he was not utterly ejected from the society and fellowship of men. For God could not only have deprived Cain of all these blessings, but he could have added pestilence, epilepsy, apoplexy, the stone, the gout, and any other disease. And yet there are men disposed curiously to argue in what manner God could possibly have multiplied the curse of Cain sevenfold on himself or on any other.
As God above deprives Cain of all the divine blessings, both spiritual—or those pertaining to the Church—and civil, so here he mitigates that sentence by commanding that no one shall slay Cain. But God does not promise at the same time that all men shall surely obey his command. Therefore Cain, even possessing this promise in reference to his body, is still a fugitive and a wanderer. And it might be that if he continued in his wickedness, he was liable to be slain at any moment; whereas, if he did well, he might live a long time. But nothing is promised him with certainty, for although these corporal or legal promises are great and important, yet they are positively uncertain and uncovenanted.
228. Whether, therefore, Cain was killed or not, I cannot with any certainty say, for the Scriptures afford no plain information upon that point. This one thing, however, evidently can be proved from the present text, that Cain had no certain promise of the preservation of his life; but God left him to a life of uncertainty, doubt and restless wandering, and did no more than protect the life of Cain by a command and a threat which might restrain the wicked from killing him, on account of the certain awful punishment which would follow such destruction of the murderer. But a promise that he should not be murdered was withheld. We know, moreover, what is the nature of the law, or a legal command, and that there are always very few who obey it. Therefore, although it is not recorded at what time, in what place, or by whom, Cain was slain, yet it is most probable that he was killed. The Scriptures however make no mention of it, even as they are quite silent also concerning the number of the years of Cain, and say nothing about the day of his birth or the day of his death. He perished, together with his whole generation; to use a popular proverb, "without cross, candle, or God." A few only of his generation are excepted, who were saved by the uncovenanted mercy of God.
229. The question is here usually asked, To what persons could the words of Cain possibly apply, when he says, "Everyone that findeth me shall slay me," when it is evident that besides Adam and Eve and their few daughters, no human beings were in existence. I would at once reply that they bear witness to the fact that we see the wicked "flee when no man pursueth," as the Scriptures say; for they imagine to themselves various perils where none really exist. Just so we see it to be the case with murderers at the present day, who are filled with fears where all is safe, who can remain quiet nowhere, and who imagine death to be present everywhere.
230. However, when it follows in the command of God, "Yea, verily, whosoever slayeth Cain shall be punished sevenfold," these words cannot be referred exclusively to the fears of Cain, for Cain had sisters, and perhaps he greatly dreaded that sister whom he had married, lest she should take vengeance on him for the murder of her brother. Moreover, Cain had perhaps a vague apprehension of a long life, and he saw that many more sons might be born of Adam. He feared, therefore, the whole posterity to Adam. And it greatly increased these fears that God had left him nothing more than his stray mercy. I do not think that Cain feared the beasts at all, or dreaded being slain by them; for what had the sevenfold vengeance threatened upon murderers to do with beasts?
V. 15b. And Jehovah appointed a sign for (set a mark upon) Cain, lest any finding him should smite him (slay him).
231. What this mark was is not to be found in the Holy Scriptures. Therefore commentators have entertained various opinions. Nearly all, however, have come to this one conclusion—they have inferred that there was apparent in Cain a great tremor of his head and of all his limbs. They suppose that, as a physical cause of his trembling, God had changed, or disarranged, or mutilated some particular organ in his body, but left the body whole as it was first created, merely adding a visible outward mark, such as the trembling. This conjecture of the fathers contains much probability, but it cannot be proved by any testimony of the Scriptures. The mark might have been of another kind. For instance, we observe in nearly all murderers an immediate change in the eyes. The eyes wear an appearance of sullen ferocity, and lose that softness and innocence peculiar to them by nature.
232. But whatever this mark was, it was certainly a most horrible punishment; for Cain was compelled to bear it during his whole life as God's penalty for the awful murder which he had committed. Rendered conspicuous by this degrading mark, hateful and abominable in the eyes of all, Cain was sent away—banished from his home by his parents. And although the life he asked of God was granted him, yet it was a life of ignominy, branded with an infamous mark of homicide; not only that he himself might be perpetually reminded of the sin he had committed, to his own confusion, but also that others might be deterred from the crime of committing murder. Nor could this mark be effaced by repentance. Cain was compelled to bear about this sign of the wrath of God upon him as a punishment in addition to his banishment, the curse, and all the other penalties.
233. It is worthy of observation that the original verb used above is harag, which signifies "to kill." But the verb here found is nakah, which means "to strike." God, therefore, here gives to Cain security, not only from death, but also from the danger of death. This security, however, as we have observed, is a legal security only; for it merely commands that no one shall slay Cain, threatening a sevenfold punishment upon the person who should do so. But God does not promise that all men will obey his command. It was far better for Cain, however, to have this legal promise made him, than to be without any promise at all.
V. 16. And Cain went out from the presence of Jehovah, and dwelt in the land of Nod, on the east of Eden.
234. This also is a very remarkable text, and it is a wonder that the fancy of the rabbins did not run riot here as usual. Moses leaves it to the thoughtful reader to reflect how miserable and how full of tears this departure of Cain from his father's house must have been. His godly parents had already lost their son Abel; and now, at the command of God, the other son departs from them into banishment, loaded with the
