Toledot - Rivka on the Camel subjugating the Nachash

Rivka on the Camel subjugating the Nachash Did Rivka fall or as Onkelus suggests gracefully dismount?  How does Rivka continue the Tikkun of Chava?  “The splendor of Yaakov was a semblance of the splendor of Adam.” Eisav had a mark resembling a nachash on his thigh; this alluded to the fact that Eisav was a representative of the nachash.   Rav Yehuda HaNasi and Antoninos שני גויים בבטנך TWO NATIONS ARE IN THY WOMB —  The True role of Eisav in this world.
