It is the glory of sheep, of oxen and of other beasts, that they feed on herbs and even on the fruits of trees, and also that they produce various things useful for the food of man, such as butter, milk, their own flesh, etc. The serpent also possessed this glory of his feeding in common with the other beasts. But now he is cast out from this society, and as it were from this common table and common feasting on account of the sin of the fall, so that he is not permitted to feed upon even the most useless herb; nor on apples, or pears, or nuts, on which even the mice feed. These he dare not taste. He eats the crude earth only. These are not my words, but the words of Moses; and they teach us that the nature of the serpent is entirely changed and wholly different from what it originally was.

And though I have said, and it is true, that it is to the serpent that God here speaks, and yet so speaks, that his words are directed all the time more expressly against Satan, as the following part of the narrative will still more plainly show; yet I am by no means satisfied that those things spoken, which rightly apply to the nature of the serpent, should be transferred allegorically, as intended to be spoken to Satan, like Augustine transfers them and is followed by Lyra. For the serpent and Satan were intimately connected in the sin of the fall, though Satan was the principal actor and the serpent only the instrument. And therefore it is that they are made alike partakers of the punishment. The serpent however bears a corporal punishment only. But for Satan, the author and agent of the whole, a different judgment is prepared, even that judgment concerning which Christ speaks, John 16:11, when he says, "Because the prince of this world is judged." The description of this judgment will now shortly follow, as recorded by Moses in the succeeding verses.

Wherefore when many say that the devil, like the serpent, no longer walks erect and that he has lost his original form and stature, the things they say are true; but they are quite inappropriate here and have nothing to do with the right interpretation of the passage now in question. And when I said above, that the serpent before the curse of God upon it moved in an erect posture, I do not wish to be understood to mean that it moved in an upright position as man, but with its neck and head erect, as a stag or a peacock. To crawl on its belly therefore after the curse, was the divine judgment on the serpent.

That which now follows belongs expressly to Satan only. And the things here recorded of him by Moses paint forth his judgment in far more true colors than any of those foolish and out-of-place descriptions of the allegorists. They moreover set before us this strong consolation, that the devil is now so situated that he cannot attack and harm us at his liberty, as he wishes to do and would do, if the Seed of the woman stood not directly in his way.

II. V. 15a. And I will put enmity between thee and the woman, and between thy seed and her seed.

These are the things which are spoken expressly and properly to Satan. And they contain his judgment. While in these same words of his judgment, there is set before the godly their strong consolation. The things above spoken are historical, as I have said, and apply to the serpent, which because through the abuse of Satan it aided in effecting the sin of Adam and Eve, bears as his part of the punishment his ejection from the common life, as it were, and from the society of the other animals of the creation; being made so different from them that he dares not eat the same food nor live in any way like them.

The present passage might also be allegorically interpreted. But the allegories used would be far less appropriate, and they would not stand firm in the defense of the truth. For the facts of the case are these: Satan on account of his sin was cast out of heaven and condemned; and no longer goes about in his original form as an ox or a hind does, but creeps on the ground; which may signify that he does not attack the godly by open force, but uses wiles and devices for their harm and destruction; which devices nevertheless the godly when they look into the Word see and understand; and by them they perceive how vast his deformity is, and hence dread and abhor him. And certainly his creeping on the ground, and not walking upright, may well indicate that his tyrannical power is broken and destroyed, so that he cannot do so much harm to the Church as he otherwise would do. These allegories, we repeat, may be used in the interpretation of the present text; but they do not explain the meaning of Moses, and therefore they are improper.

Wherefore, when we speak of Satan, let us ever follow the other testimonies of Scripture upon the subject; for they are proper, certain and sure; such for instance as the following: "The devil was a murderer from the beginning, and standeth not in the truth, because there is no truth in him;" and also, "When he speaketh a lie he speaketh of his own," John 8:44; and again, "Your adversary the devil, as a roaring lion, walketh about seeking whom he may devour," 1 Pet. 5:8; and also, where Christ says, "The prince of this world is judged," John 16:11.

In a word, who does not plainly see that the testimony of the present passage applies properly to Satan; and that it is to him that the Son of God is here opposed, expressly to prevent him from making any attack upon us with open violence, as if he had no certain Antagonist! The Church therefore, under this protection, is perfectly safe. And not only is Satan deprived of the power of attacking the Church with any open violence, but his power and desire of harming anything or person else are also destroyed. Were it not so, he would not suffer a single tree to grow to maturity. He would impede and crush all things that spring forth in the earth; and would prevent, not the birth of men only, but the bringing forth of beasts; and would destroy the safety of everything. This insatiable desire to harm and to destroy is fully manifest from his inability to attack by open violence, and from his doing whatever he does by the means of craft, guile and snare.

We should here moreover carefully observe that these things are not spoken by God for the devil's sake. For God does not deign to condemn Satan on his own account, by these his words; but he deems it sufficient to leave Satan to be condemned by his own conscience. All that God speaks to Satan, he speaks for the sake of Adam and Eve; that they may hear this judgment of God upon him and may comfort themselves, by thus hearing and seeing that God is the adversary to the nature of him, who had inflicted such a wound on man. For out of these very words of God to Satan, there begin to shine forth grace and mercy; yea, out of the very midst of that anger, which sin and disobedience had so righteously kindled. It is here in the very midst of the heaviest threatenings, that the mind of the Father discloses itself; of a Father, not so angry as to cast away his Son, but holding out salvation, yea, promising victory over that enemy, who had thus deceived and conquered human nature.
