The serpent now makes a strong and bold assertion, denying the deadly efficacy of the tree, or the fatal consequence of partaking of it, and affirming that God was aware that on the eating of it their eyes would be opened, and they would be like himself in knowing good and evil.

Let us remember that this was the first falsehood the woman ever heard. Her mind was also infantile as yet, so far as experience was concerned. The opening mind is naturally inclined to believe the truth of every assertion, until it has learned by experience the falsehood of some. There was also in this falsehood what gives the power to deceive, a great deal of truth combined with the element of untruth. The tree was not physically fatal to life, and the eating of it really issued in a knowledge of good and evil. Nevertheless, the partaking of what was forbidden issued in the legal and actual privation of life. And it did not make them know good and evil altogether, as God knows it, but in an experimental sense, as the devil knows it. In point of knowledge, they became like God; in point of morality, like the tempter.

Ye shall not surely die - Here the father of lies at once appears; and appears too in flatly contradicting the assertion of God. The tempter, through the nachash, insinuates the impossibility of her dying, as if he had said, God has created thee immortal, thy death therefore is impossible; and God knows this, for as thou livest by the tree of life, so shalt thou get increase of wisdom by the tree of knowledge.

And the serpent said unto the woman,.... In reply to her answer:

ye shall not surely die; in direct contradiction to the divine threatening, and which he would insinuate was a mere threatening, and which God never intended to put in execution; so that they had nothing to fear from that, God would never be so rigid and severe, and beat so hard upon them as to put them to death for such an offence, if it was one; he only gave out the menace to frighten them, and deter from it: however, at most it was not a certain thing they should die, and they might safely conclude they would not.

And the serpent said unto the woman, Ye shall not surely {d} die:

(d) This is Satan's chiefest subtilty, to cause us not to fear God's warnings.

3:1-5 We have here an account of the temptation wherewith Satan assaulted our first parents, and which proved fatal to them. And here observe, The tempter, the devil in the shape of a serpent. Multitudes of them fell; but this that attacked our first parents, was surely the prince of the devils. Whether it was only the appearance of a serpent, or a real serpent, acted and possessed by the devil, is not certain. The devil chose to act his part in a serpent, because it is a subtle creature. It is not improbable, that reason and speech were then the known properties of the serpent. And therefore Eve was not surprised at his reasoning and speaking, which otherwise she must have been. That which the devil aimed at, was to persuade Eve to eat forbidden fruit; and to do this, he took the same method that he doth still.
1. He questions whether it were a sin or no, Ge 3:1,2. He denies that there was any danger in it, Ge 3:4.
3. He suggests much advantage by it, Ge 3:5. And these are his common topics. As to the advantage, he suits the temptation to the pure state they were now in, proposing to them not any carnal pleasure, but intellectual delights. Your eyes shall be opened - You shall have much more of the power and pleasure of contemplation than now you have; you shall fetch a larger compass in your intellectual views, and see farther into things than now you do. You shall be as gods - As Elohim, mighty gods, not only omniscient but omnipotent too: You shall know good and evil - That is, everything that is desirable to be known. To support this part of the temptation, he abuseth the name given to this tree. 'Twas intended to teach the practical knowledge of good and evil, that is, of duty and disobedience, and it would prove the experimental knowledge of good and evil, that is, of happiness and misery. But he perverts the sense of it, and wrests it to their destruction, as if this tree would give them a speculative notional knowledge of the natures, kinds, and originals of good and evil. And, All this presently, In the day you eat thereof - You will find a sudden and immediate change for the better.

4. Ye shall not surely die-He proceeded, not only to assure her of perfect impunity, but to promise great benefits from partaking of it.

3:1-5 Satan assaulted our first parents, to draw them to sin, and the temptation proved fatal to them. The tempter was the devil, in the shape and likeness of a serpent. Satan's plan was to draw our first parents to sin, and so to separate between them and their God. Thus the devil was from the beginning a murderer, and the great mischief maker. The person tempted was the woman: it was Satan's policy to enter into talk with her when she was alone. There are many temptations to which being alone gives great advantage; but the communion of saints tends very much to their strength and safety. Satan took advantage by finding her near the forbidden tree. They that would not eat the forbidden fruit, must not come near the forbidden tree. Satan tempted Eve, that by her he might tempt Adam. It is his policy to send temptations by hands we do not suspect, and by those that have most influence upon us. Satan questioned whether it were a sin or not, to eat of this tree. He did not disclose his design at first, but he put a question which seemed innocent. Those who would be safe, need to be shy of talking with the tempter. He quoted the command wrong. He spoke in a taunting way. The devil, as he is a liar, so he is a scoffer from the beginning; and scoffers are his children. It is the craft of Satan to speak of the Divine law as uncertain or unreasonable, and so to draw people to sin; it is our wisdom to keep up a firm belief of God's command, and a high respect for it. Has God said, Ye shall not lie, nor take his name in vain, nor be drunk, &c.? Yes, I am sure he has, and it is well said; and by his grace I will abide by it. It was Eve's weakness to enter into this talk with the serpent: she might have perceived by his question, that he had no good design, and should therefore have started back. Satan teaches men first to doubt, and then to deny. He promises advantage from their eating this fruit. He aims to make them discontented with their present state, as if it were not so good as it might be, and should be. No condition will of itself bring content, unless the mind be brought to it. He tempts them to seek preferment, as if they were fit to be gods. Satan ruined himself by desiring to be like the Most High, therefore he sought to infect our first parents with the same desire, that he might ruin them too. And still the devil draws people into his interest, by suggesting to them hard thoughts of God, and false hopes of advantage by sin. Let us, therefore, always think well of God as the best good, and think ill of sin as the worst evil: thus let us resist the devil, and he will flee from us.
