פּירוש אויף בראשית 3:12

אשר נתת עמדי WHOM THOU GAVEST TO BE WITH ME — Here he showed his ingratitude (Avodah Zarah 5b).

Once he saw that one cannot cover up before the One that knows all secrets, he confessed against his will and said, "The iniquity is not upon me, but rather upon the woman." The woman said, "The iniquity is upon the serpent." As this is the way of thieves - when they are caught, they give away one another. The serpent did not find an answer, for we do not [allow] an inciter to make a claim - as our Rabbis said (Sanhedrin 29a): As even though they should not have listened to him - for [in a case of] the words of the teacher and the words of the student, to whom does one listen - nevertheless, he should not have entrapped [them], as they transgressed the commandment of the Creator. And they all confessed that they transgressed - as the Holy One said to Adam, "Because you listened to the voice of your wife, (Genesis 3:17) more than [to] My voice." And all the more so, the woman should not have listened to the serpent, who was not her friend and advisor. Hence Scripture said to Adam, "Because you listened to the voice of your wife"; whereas it did not say to the woman, "Because you listened to the voice of the serpent." As it an a fortiori argument, so there is no need [to say it]. And the Holy One, blessed be He, began to curse them in the way that they did the transgression: The snake that started was cursed first, and Adam afterwards.

האשה אשר נתתה עמדי, “the woman You have given me to be my companion;” Adam complains that this woman who had been meant to be his helper, assistant, had instead turned out to be his seducer. He had assumed that he could trust her implicitly. He claimed that he had not known from which tree she had taken the fruit she offered him. The Torah had not mentioned which fruit she had asked him to share, i.e. the fruit of the tree of knowledge. Adam implied that if he had known that this was the fruit of the tree of knowledge he would not have eaten from it. Had he refused her offer of the fruit, he would have appeared as ungrateful, for how could he refuse something that G-d had provided, seeing that only good things emanate from G-d. (Compare Avodah Zarah, 5)
