Moshe's parents were Amram and Yocheved. In addition to being the wife of Amram, Yocheved was also Amram's aunt! Post Matan Torah this relationship would be prohibited but because the Torah had not yet been given there was no issur in their relationship. The question is, why was this unique union necessary? How did it impact the future development of Moshe Rabbeinu?
In this shiur (based on the approach of the Maor Vashemesh) Rav Burg explores the inner nature of masculinity and femininity and how Moshe Rabbeinu developed dominant, female humility.
