"Let me go, for the day breaks"
Here, Rabbi Elazar tells how Jacob wrestled all night with the Appointed Angel of Esau, Samael - though until dawn he thought he was wrestling with Esau. He struck the Angel, who said "Let me go, for the day breaks," because the Angel and his female, Lilit, have dominion only at night. We are then told that when morning arrived Samael and his friends entered the hole of the great Abyss in the North. Another explanation of "Let me go, for the day breaks," is that night stands for the exile of the children of Yisrael, during which the wicked idol-worshipping kingdom dominates them until morning, when the Redemption arrives and the Holy One shines for them. Jacob, we next learn, would not let the Angel go unless He blessed him, which He did. Jacob saw in Esau's face the exact image that he saw in Samael, because, we are told, whatever a person is connected to is reflected in his face. And again Rabbi Elazar tells the three rabbis that because the Shechinah is with them, he sees their faces are like Hers.
Strength to wrestle and conquer our own fears and dark side is bestowed upon us. This radiance shines into our darkest moments so that what we see illuminated before us is always the truth, not just a shadow of the truth. Moreover, this Light relinquishes the hold of the two negative angels, Samael and Lilit, over all mankind, freeing us forever from their deadly grip. Now that we have total control and dominance over the root of evil - through the greatness and spiritual prowess of Jacob - we are free to complete our personal ascension and actuate the Final Redemption in a softhearted and merciful manner.
