Genesis 4:7

7. If thou does well. In these words God reproves Cain for having been unjustly angry, inasmuch as the blame of the whole evil lay with himself. For foolish indeed was his complaint and indignation at the rejection of sacrifices, the defects of which he had taken no care to amend. Thus all wicked men, after they have been long and vehemently enraged against God, are at length so convicted by the Divine judgment, that they vainly desire to transfer to others the cause of the evil. The Greek interpreters recede, in this place, far from the genuine meaning of Moses. Since, in that age, there were none of those marks or points which the Hebrews use instead of vowels, it was more easy, in consequence of the affinity of words to each other, to strike into an extraneous sense. I however, as any one, moderately versed in the Hebrew language, will easily judge of their error, I will not pause to refute it. Yet even those who are skilled in the Hebrew tongue differ not a little among themselves, although only respecting a single word; for the Greeks change the whole sentence. Among those who agree concerning the context and the substance of the address, there is a difference respecting the word שאת(seait,) which is truly in the imperative mood, but ought to be resolved into a noun substantive. Yet this is not the real difficulty; but, since the verb נשא (nasa,) signifies sometimes to exalt, sometimes to take away or remit, sometimes to offer, and sometimes to accept, interpreters very among themselves, as each adopts this or the other meaning. Some of the Hebrew Doctors refer it to the countenance of Cain, as if God promised that he would lift it up though now cast down with sorrow. Other of the Hebrews apply it to the remission of sins; as if it had been said, ‘Do well, and thou shalt obtain pardon’. But because they imagine a satisfaction, which derogates from free pardon, they dissent widely from the meaning of Moses. A third exposition approaches more nearly to the truth, that exaltation is to be taken for honor, in this way, ‘There is no need to envy thy brother’s honor, because, if thou conductest thyself rightly, God will also raise thee to the same degree of honor; though he now, offended by thy sins, has condemned thee to ignominy.’ But even this does not meet my approbation. Others refine more philosophically, and say, that Cain would find God propitious and would be assisted by his grace, if he should by faith bring purity of heart with his outward sacrifices. These I leave to enjoy their own opinion, but I fear they aim at what has little solidity. Jerome translates the word, ‘Thou shalt receive;’ understanding that God promises a reward to that pure and lawful worship which he requires. Having recited the opinions of others, let me now offer what appears to me more suitable. In the first place, the word שאת means the same thing as acceptance, and stands opposed to rejection. Secondly, since the discourse has respect to the matter in hand, I explain the saying as referring to sacrifices, namely, that God will accept them when rightly offered. They who are skilled in the Hebrew language know that here is nothing forced, or remote from the genuine signification of the word. Now the very order of things leads us to the same point: namely, that God pronounces those sacrifices repudiated and rejected, as being of no value, which are offered improperly; but that the oblation will be accepted, as pleasant and of good odour, if it be pure and legitimate. We now perceive how unjustly Cain was angry that his sacrifices were not honored seeing that God was ready to receive them with outstretched hands, provided they ceased to be faulty. At the same time, however; what I before said must be recalled to memory, that the chief point of well-doing is, for pious persons, relying on Christ the Mediator, and on the gratuitous reconciliation procured by him, to endeavor to worship God sincerely and without dissimulation. Therefore, these two things are joined together by a mutual connection: that the faithful, as often as they enter into the presence of God, are commended by the grace of Christ alone, their sins being blotted out; and yet that they bring thither true purity of heart.

And if thou does not well. On the other hand, God pronounces a dreadful sentence against Cain, if he harden his mill in wickedness and indulge himself in his crime; for the address is very emphatical, because God not only repels his unjust complaint, but shows that Cain could have no greater adversary than that sin of his which he inwardly cherished. He so binds the impious man, by a few concise words, that he can find no refuge, as if he had said, ‘Thy obstinacy shall not profit thee; for, though thou shouldst have nothing to do with me, thy sin shall give thee no rest, but shall drive thee on, pursue thee, and urge thee, and never suffer thee to escape.’ Hence it follows, that he not only raged in vain and to no profit; but was held guilty by his own inward conviction, even though no one should accuse him; for the expression, ‘Sin lieth at the door’, relates to the interior judgement of the conscience, which presses upon the man convinced of his sin, and besieges him on every side. Although the impious may imagine that God slumbers in heaven, and may strive, as far as possible, to repel the fear of his judgment; yet sin will be perpetually drawing them back, though reluctant and fugitives, to that tribunal from which they endeavor to retire. The declarations even of heathens testify that they were not ignorant of this truth; for it is not to be doubted that, when they say, ‘Conscience is like a thousand witnesses,’ they compare it to a most cruel executioner. There is no torment more grievous or severe than that which is hence perceived; moreover, God himself extorts confessions of this kind. Juvenal says: —
