Rashi on Genesis 3:17/רש"י על בראשית ג׳:י״ז

1ארורה האדמה בעבורך CURSED BE THE GROUND FOR THY SAKE — It will produce to you cursed objects such as flies, fleas and ants; it may be compared to the case of one who gets into depraved ways, and people curse the breasts at which he was suckled (Genesis Rabbah 5:9).
