As a reply to both queries on korbanos and the story of Yaakov's blessing.
You should look up chassidic text who explain the meaning of the korbanos
in "our" spiritual services and the reason why the blessing of Yaakov had
to come in such a way. Without knowing who I am writing to it's hard to
recommend a specific text but if you Hebrew is good look up Torah Or (on
bereishis) and Likkutei Torah on Vayikra from Rabbi Schneur Zalman of
Liady, the Baal Hatanya.
