But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.

But of the tree of knowledge of good and evil, thou shalt not eat. for in what day soever thou shalt eat of it, thou shalt die the death.

but of the tree of the knowledge of good and evil, thou shalt not eat of it; for in the day that thou eatest of it thou shalt certainly die.

and of the tree of knowledge of good and evil, thou dost not eat of it, for in the day of thine eating of it, dying thou dost die.'

But from the tree of the knowledge of good and evil, you shall not eat. For in whatever day you will eat from it, you will die a death."

At de arbore scientiae boni et mali ne comedas ex illa: quia in die quo comederis ex ea, moriendo morieris.

Of the tree of the knowledge - thou shalt not eat - This is the first positive precept God gave to man; and it was given as a test of obedience, and a proof of his being in a dependent, probationary state. It was necessary that, while constituted lord of this lower world, he should know that he was only God's vicegerent, and must be accountable to him for the use of his mental and corporeal powers, and for the use he made of the different creatures put under his care. The man from whose mind the strong impression of this dependence and responsibility is erased, necessarily loses sight of his origin and end, and is capable of any species of wickedness. As God is sovereign, he has a right to give to his creatures what commands he thinks proper. An intelligent creature, without a law to regulate his conduct, is an absurdity; this would destroy at once the idea of his dependency and accountableness. Man must ever feel God as his sovereign, and act under his authority, which he cannot do unless he have a rule of conduct. This rule God gives: and it is no matter of what kind it is, as long as obedience to it is not beyond the powers of the creature who is to obey. God says: There is a certain fruit-bearing tree; thou shalt not eat of its fruit; but of all the other fruits, and they are all that are necessary, for thee, thou mayest freely, liberally eat. Had he not an absolute right to say so? And was not man bound to obey?
Thou shalt surely die - מות תמות moth tamuth; Literally, a death thou shalt die; or, dying thou shalt die. Thou shalt not only die spiritually, by losing the life of God, but from that moment thou shalt become mortal, and shalt continue in a dying state till thou die. This we find literally accomplished; every moment of man's life may be considered as an act of dying, till soul and body are separated. Other meanings have been given of this passage, but they are in general either fanciful or incorrect.

But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely (m) die.
(m) By death he means the separation of man from God, who is our life and chief happiness: and also that our disobedience is the cause of it.

But of the tree of knowledge of good and evil,.... Of the name of this tree, and the reasons of it; see Gill on Genesis 2:9.
thou shalt not eat of it; not that this tree had any efficacy in it to increase knowledge, and improve in science and understanding, as Satan suggested God knew; and therefore forbid the eating of it out of envy to man, which the divine Being is capable of; or that there was anything hurtful in it to the bodies of men, if they had eaten of it; or that it was unlawful and evil of itself, if it had not been expressly prohibited: but it was, previous to this injunction, a quite indifferent thing whether man ate of it or not; and therefore was pitched upon as a trial of man's obedience to God, under whose government he was, and whom it was fit he should obey in all things; and since he had a grant of all the trees of the garden but this, it was the greater aggravation of his offence that he should not abstain from it:
for in the day thou eatest thereof thou shalt surely die; or "in dying, die" (z); which denotes the certainty of it, as our version expresses it; and may have regard to more deaths than one; not only a corporeal one, which in some sense immediately took place, man became at once a mortal creature, who otherwise continuing in a state of innocence, and by eating of the tree of life, he was allowed to do, would have lived an immortal life; of the eating of which tree, by sinning he was debarred, his natural life not now to be continued long, at least not for ever; he was immediately arraigned, tried, and condemned to death, was found guilty of it, and became obnoxious to it, and death at once began to work in him; sin sowed the seeds of it in his body, and a train of miseries, afflictions, and diseases, began to appear, which at length issued in death. Moreover, a spiritual or moral death immediately ensued; he lost his original righteousness, in which he was created; the image of God in him was deformed; the powers and faculties of his soul were corrupted, and he became dead in sins and trespasses; the consequence of which, had it not been for the interposition of a surety and Saviour, who engaged to make satisfaction to law and justice, must have been eternal death, or an everlasting separation from God, to him and all his posterity; for the wages of sin is death, even death eternal, Romans 6:23. So the Jews (a) interpret this of death, both in this world and in the world to come.

thou shalt not eat of it . . . thou shalt surely die--no reason assigned for the prohibition, but death was to be the punishment of disobedience. A positive command like this was not only the simplest and easiest, but the only trial to which their fidelity could be exposed.
