Kommentar zu Bereschit 3:13

השיאני means HE DECEIVED ME; — we find the word in the same meaning in (2 Chronicles 32:15), “Now therefore let not Hezekiah beguile you” (Genesis Rabbah 19).

WHAT IS THIS THOU HAST DONE to transgress My commandment? For the woman was included in the admonition given to Adam since at that time she was yet bone of his bones, and similarly she was included in his punishment. The reason why G-d did not say to the woman, “and thou hast eaten of the tree,” is that she was punished for both her eating and her advice, just as the serpent was punished for the advice. This is why she said, The serpent beguiled me, and I did eat,³⁹²In the verse before us. Thus she mentioned both the eating and the advice. as the punishment for the beguiling was greater than that for the eating. [Hence as soon as she mentioned that the serpent beguiled her, G-d meted out his punishment immediately, as is stated in the following two verses.] Thus we may derive from here the principle of punishment for those that cause people to sin in any matter, just as our Rabbis have derived it from the verse, Thou shalt not put a stumbling-block before the blind.³⁹³Leviticus 19:14. In Pesachim 22 b, the verse is interpreted to mean: do not give a person who is “blind” in a matter advice which is improper for him. Advising or causing one to sin is thus included in this prohibition. Ramban is here suggesting that while the admonition against causing people to sin is derived from the verse in Leviticus, the principle of punishment for such advice is derived from here.

What is this that you have done. Hashem said this to arouse her to repent.
