Musar su Ezechiele 16:7

Since the havoc wrought on G–d's creation was due to the original נחש, and that serpent was ערום, sly, or naked, i.e. brazen, Israel descended into the "iron crucible" of Egypt to experience ערום ועריה (Ezekiel 16,7), facing Pharaoh who is described elsewhere as the תנין הגדול, the great sea monster, the serpent being עפר לחמו, having been condemned to subsist on dust (Genesis 3,14). The letters in the name Pharaoh, i.e. פרעה when re-arranged spell העפר "the dust." This is the reason the first miracle Moses performed transformed the staff into a תנין to allude to Pharaoh. In order to cleanse themselves spiritually from the pollutant of the original serpent, Israel had to perform עבודת פרך, hard labour. Since the pollutant of that serpent had kept permeating more and more of the human being, it required potent cleansing measures to eradicate it. Had there not been such a pollutant, man would have lived indefinitely. As it is, the only two means to regain the original state of man are afflictions while he is alive, and the experience of death itself. Exile is one of the manifestations of such afflictions. So we have a progression of afflictions which will culminate in serenity, light, until the original light of creation which has been hidden will be revealed again. Nowadays the world is desolate, due to the sin caused by the נחש, i.e. our sins. Physical death is described in Genesis as טוב מאד, very good according to Rabbi Meir (Genesis 1,31). This is because it is the catalyst that leads man to repentance and thereby to eternal life and resurrection (Midrash Hagadol).

Bereshit Rabbah 60,13 points out that as a result of Laban's blessing in Genesis 24,60: אחותנו את היי לאלפי רבבות, "Our sister! May you grow into thousands and tens of thousands," "thousands" i.e. אלו תימן, אלוף קנז, are descended from her through Esau, and "tens of thousands" i.e. רבבה כצמח השדה נתתיך, through Jacob as per Ezekiel 16,7. Laban eventually conceded the validity of these blessings. Even the part which was negative, i.e. the blessings for Esau, Laban "purified," i.e. he agreed for Esau to embrace true monotheism. This is evident from Laban's words in Genesis 24,50 "This matter was decreed by G–d; we cannot speak to you either bad or good." Laban acknowledges that everything is in the hands of G–d, and he says "here is Rebeccah, take her and go."
