פּירוש אויף בראשית 3:4

לא מות תמתון YE SHALL NOT SURELY DIE — He pushed her until she touched it. He then said to her, “Just as there is no death in touching it, so there is no death in eating it” (Genesis Rabbah 19:3).

ויאמר, the serpent in its craftiness, said: לא מות תמותון, not as you say that G’d loves you so much that He forbade eating you to protect you from dying, but the reason is that not only will you not die from eating, but He made you more afraid so that you will not acquire the additional advantage by eating from it,

לא מות תמותון “you will sure not die, כי יודע אלוקים כי בים אכלכם ממנו ונפקחו עיניכם, G’d did not forbid this fruit because it is lethal, but because He knows that through eating it you will attain additional knowledge so that you will be just like G’d, possessing total knowledge.
