219. The Lord, accordingly, does not in this passage at all alter the sentence upon Cain whereby he had been doomed to a curse on earth, but merely vouchsafes to him this uncovenanted mercy for the sake of the elect that are to be saved from that curse as from a mass of dregs. That is the reason he said Cain should not be killed, as he feared.
There is, then, no necessity for doing violence to this text as Rabbi Solomon does, who, after the words "whosoever slayeth Cain," puts a stop; making it to be a hiatus or (ellipsis), as we find in that noted line in Virgil (Aeneas, 135)—
Quos ego—sed motos praestat componere fluctus.
Whom I—but now, be calm, ye boist'rous waves.
And then the expression, "shall be punished sevenfold," the rabbi refers to Cain himself, who was punished in his seventh generation. For Cain begat Enoch, and Enoch begat Irad, and Irad begat Mehujael, and Mehujael begat Methusael, and Methusael begat Lamech.
220. And the Jews' absurd comment upon that passage (verse 23, below), is that Lamech, when he was old, and his eyes dim, was taken by his son Tubal-Cain into a wood to hunt wild beasts, and that, when there shooting at a wild beast, Lamech accidently shot Cain, who in his wanderings had concealed himself in the wood. Such interpretations are only fables, unworthy a place or notice in our schools. Moreover, they militate against the very truth of the text. For if Cain was really designed of God to be killed in the seventh generation, and if that time was thus fixed for his death, he was not "a fugitive and a vagabond upon earth."
221. We condemn, therefore, this interpretation of Rabbi Solomon, on the ground of critical discrimination, because it militates directly against that sentence which God had before pronounced; and God is not man, that he should change his mind, 1 Kings 15, 29-30. This rule should be strictly observed in all interpretation of the Holy Scripture, that the rendering of one passage must not subsequently conflict with that of another. And when the rabbins, moreover, say that the deluge was the particular punishment of Lamech's sin in thus killing Cain, Lyra refutes them. He very truly affirms that the deluge was the common punishment of the whole world of wicked men. We leave, therefore, all these Jewish absurdities and hold fast the true meaning of the text before us, that, when Cain feared lest he should be slain by any one who should find him, the Lord prevented him from being thus slain, and denounced on such murderer a punishment sevenfold greater than that of Cain.
222. And, though Lyra argues and inquires how it could be that he who should slay Cain could deserve a sevenfold greater vengeance than Cain deserved, who slew his own brother, of what profit is it to us to inquire into the counsel of God in such matters as these, especially when it is certain that God permitted his mercy to stray to Cain in the form of promises and blessings under the Law, if I may so express myself, thus securing his safety.
