John Calvin's Bible Commentary
Deuteronomy 18:10
10.There shall not be found among you. This horrible and altogether monstrous infatuation, whereby the Gentiles had been possessed, afterwards invaded the Jews also, that they should immolate and even burn their children in honor of the gods to which they had devoted themselves; although it is probable that the greater part of them were not inflamed by such an excess of madness, but satisfied their superstition more easily, by merely making their children to pass through the fire. This was with them a kind of lustration to purge away all filthiness. But their cruel zeal impelled many of them even to murder, so as not even to spare their own flesh and blood. Yet in this they pleaded the example of Abraham, as if there were any similarity between the obedience of that holy man who, led by God’s command, was ready to slay his son Isaac, and this barbarous act of violence in people who, though God prohibited and gainsaid, murdered their children. Yet in this horrible spectacle we perceive how much more fervently men engage in impious rites which their own temerity has dictated, than in efforts to worship God aright, when He openly and expressly enjoins them the thing that is good. This, indeed, ought to be the first care of parents to consecrate their children to God; but the only rite of initiation for the Jews was circumcision, and with this they should have been content. Moses then enumerates the various kinds of divination to which the heathen nations were addicted, in order to satisfy their foolish desire to know more than was lawful. I do not, however, disapprove of the view which some prefer, (282) that the generic term is first used, and the various species are then subjoined. I shall explain these briefly, and not waste time in refuting particular opinions, although it is evident that even some of the rabbis are grossly mistaken about them. The word מעונן , (283) magnonen, I willingly admit to be derived from (a word signifying) clouds; and therefore it may properly mean augurs, or judicial astrologers. There are some who are rather of opinion that its root is מגון , magnon, which in Hebrew means a place; and this etymology would not badly suit the fanatics who divine all things from the position of the stars, and assign their stations both to the planets and the signs of the zodiac for their respective aspects. At any rate this is fully agreed, that auguries, as well as frivolous observations of the stars, are here condemned, when men, in their preposterous curiosity, suppose all events and circumstances to be under the dominion of the stars. The word which follows מנחש , (284) menachesh, means a diviner or soothsayer, (ariolum,) which sufficiently appears from Genesis 44:5, where Joseph pretends that he divined by his cup, because it was commonly believed that he possessed the art of soothsaying; and hence the name has been given to serpents on account of their subtlety. Some interpret the word מכשף, (285) mekasheph, a juggler, (praestigiatorem,) one who dazzles and deceives the eyes by optical illusions. Next follows the fifth (286) term, which I have translated “tying knots,” (colligans colligationes,) whereby some understand enchanters, who by magic arts gather together serpents into one place. But this, in my judgment, is a poor explanation, and I, therefore, rather agree with those who conceive the calling together of evil spirits to be alluded to. But since it may be correctly translated “collecting, or gathering an assembly,” I do not altogether reject the opinion of others, that it relates to those imaginary assemblies, to which unhappy men, whom the devil has bewitched, fancy themselves to be transported to feast and dance together, and to join in wicked conspiracies, and which are commonly called “synagogues.” In the sixth word there is no ambiguity, whereby the people are forbidden to consult a spirit of Python; for thus may we properly render the Hebrew אוב, (287) ob, as St. Luke, a faithful and competent interpreter, has done, when he relates that a spirit of Python was cast out of the damsel at the command of Paul, ( Acts 16:16;) and sometimes the Scripture calls these by the name of אובות, oboth, who allure evil spirits to give replies, of which deception a remarkable example is given in sacred history, ( 1 Samuel 28:7,) in the case of the witch (Pythonissa) who shewed Saul Samuel, although dead. The Greeks have translated the word Python, because the delusions of Apollo Pythius were particularly famous. The seventh class (Ang., wizards) is ידעני, (288) yadgnoni, which may correctly be translated gnostics, or knowers; for I make no doubt that they adopted this honorable name for purposes of deceit, which is by no means an uncommon practice with impostors. Thus the Genethliacs, and others like them, vaunted themselves to be mathematicians. This is the craft of Satan to steal the respectable names of virtues and good things, and to make them a covering for his lies, as, for instance, he gave the name of wise men to the Chaldean and Egyptian impostors; and thus, since the Prophets are called seers, he set against them the vain prognostications of false prophets, to astonish the minds of the simple. (289) For to derive, as some do, this word from a certain bird, is too childish a conjecture; and I wonder that in such a plain matter they have been led so utterly astray, whilst they waste their acuteness upon nothing. Finally, necromancy (290) is condemned, i.e., the deceitful and delusive science of prophesying upon the answers of the dead, which some improperly restrict to those who sleep among tombs, in order to hear in their sleep the dead speaking, because foolish men have in many ways endeavored to obtain communications from the dead. But, let us learn from this passage, with how many monstrous and ridiculous fascinations Satan, whenever God loosens the chain by which he is bound, is able to bewitch unhappy men; and how great, power to deceive the father of lies obtains from the just vengeance of God, for the purpose of blinding unbelievers. As to the notion which some conceited persons entertain, that all these things are fabulous and absurd, it arises from inconsideration and presumption, because they do not reflect how severe a judgment is merited by those who wilfully extinguish the light and enwrap themselves in darkness. For God’s truth is too precious to Him, for Him to suffer it to be rejected with impunity. Certainly it would be an impudent blasphemy to deny that magical arras were ever practiced, since thus would God be accused of inadvertency, as though He had legislated (291) respecting things which did not exist. The objection that is made of its being absurd thus too highly to extol the power of Satan, as if he had the control of prophecies, which God claims for Himself alone, and as if he could cause the living to converse with the dead and change the forms of things, admits of an easy solution. With respect to vaticinations, there is no necessity for a subtle discussion as to how Satan can foreknow secret things, (on which point, as it seems to me, Augustine troubled himself too anxiously,) for this is a labor of supererogation, if we recollect that by God’s just judgment a certain kind of vaticination is permitted to the devils, in order more and more to deceive unbelievers, as will be more fully treated of elsewhere. Meanwhile, we know that unbelievers were mocked with (292) ambiguous responses by all the oracles of false gods, and at length discovered from the event that they had been beguiled by deadly artifices; and, therefore, in Isaiah 41:23, God justly charges every idol with ignorance of futurity. Yet this does not prevent Satan from revealing certain hidden matters, by the prediction of which he may ensnare, as by a bait, the reprobate. I admit, indeed, that in progress of time the Roman augurs abandoned the study of their art, and abused the credulity of the lower orders by nothing but gross fictions; but if in former times Satan had not led even the most sharp-sighted into error by this artifice, Xenophon, (293) the disciple of Socrates, would not have so often mentioned among the chief praises of Cyrus, (294) that he was devoted to augury, and had learnt to be so from his father. Finally, the experience of all ages teaches us that men of depraved curiosity have often received from Satan, by means of magicians, a knowledge of things which could not have been obtained naturally. As to the actual operations of Satan, whether he raises the dead, or bewitches men and beasts, or invests any substances with new forms through enchantment, we must consider that whatever miracles he appears to work are mere delusions; and, since he is the father of darkness, it is clear he has no power except upon unbelievers, whose minds are darkened, so as not to distinguish black from white. Yet we have already seen how Pharaoh’s magicians rivalled Moses in their miracles. Wherefore we need not wonder if, by God’s permission, he should disturb the elements, or afflict the reprobate with diseases and other evils, or present phantoms to their sight. On this account we should more earnestly implore of God to restrain from us an enemy armed against us with so many destructive arts.
