John Calvin's Bible Commentary
Exodus 9:27
27.And Pharaoh sent and called. If this confession had proceeded from the heart, it would have betokened repentance; but Moses immediately perceived that fear in the heart of the wicked is not a principle which governs them in lasting duty; (111) and this was more manifest in the result.
Although we must, at the same time, recollect, what I have already touched upon, that Pharaoh did not lie designedly; for when seized by terror, he caught at every means to appease God, but soon after relapsed into his former state of mind. For although with fox-like cunning the wicked pretend submission, when they see themselves caught, in order to escape from the snare, still they do not mean to mock God by their soft words; but rather under the pressure of necessity they are ready to do anything, and therefore offer propitiation’s and satisfactions; but when their fear has departed, because whatever they promised was forcibly extorted from them, they directly break out afresh. A very similar circumstance is related of Saul. He confesses to his own disgrace the innocence of David, and yet, as soon as he has escaped from the danger, and is freed from fear, he does not cease to persecute him cruelly. (1 Samuel 24:18, and 1 Samuel 26:21.) But if we admit that this was mere dissimulation, Pharaoh had greater cause for fear, because, being experimentally convinced that God was his adversary, he was impelled by his fear to make any conditions whatever. But, first of all, he acknowledges that he had “sinned this time,” not to excuse the former cases, but. because, in such gross contempt, the crime of obstinacy was still more detestable. And this more fully appears in the following words, wherein he acknowledges the justice of God, and confesses the wickedness of himself and his people. It is just as if he had said, that he is deservedly punished, because he had too long provoked God, who is a just judge. Now since, as far as his words go, Pharaoh professes true repentance, we may gather from them, that, sinners do not attribute to God the honor due to His justice, unless they condemn themselves; and this must be more carefully observed, because there are few who think that, while they are endeavoring to rebut the accusations of guiltiness, they are dishonoring God. Yet, whosoever does not judge himself, and who does not frankly confess his sins, is assuredly murmuring against the judgment of God. Pharaoh, at length, has recourse to deprecation, in which he desires to have Moses and Aaron as his intercessors; not, I admit, without deception, (because hypocrites are always double-hearted;) yet it is certain, that because he was terrified by his troubles, he sought for peace with God, lest his rebellion should draw down upon him new and greater punishments; but as soon as, having obtained his desire, he ceased to be afraid, the secret wickedness which lay, as it were, stifled under the abundance of his miseries, burst forth out of the sense of security. What immediately follows is variously explained by the translators; some understand it negatively, “that there be not,” or “if there be not — thunderings;” and even these disagree among themselves; for some suppose that Pharaoh congratulates himself, because the thunders have ceased; but it is plain from the context that they are grossly mistaken. If, then, a negation is intended, the passage must necessarily refer to the future; as if Pharaoh had said, that he should be very graciously dealt with, if God should please to allay the thunderings. (112) But the various reading is equally probable; “It is much, or a great thing, that there are, or have been thunderings;” as though he said, that he had been punished enough, or more than enough for his folly; or (as best pleases myself) that he is now subdued by terror, whilst he is alarmed by the continual rollings of the thunder and the beating of the hail; for he seems to desire to prove the truth of his conversion, because he is conquered by the terrible power of God.
