I had a theory, [which I subsequently found in Pirkei D'Rav Eliezer chapter 24] regarding the Coat that Yaakov gave to Yosef that engendered so much jealousy from the brothers
Adam Harishon had a special coat that had a special power that would attract animals to it (See Pirkei D'Rav Eliezer 24) . The coat went from Noach to Cham and was then given to Nimrod. Later we know that Eisav killed Nimrod and took the coat. (Ibid.)
Later we learn the story of Yaakov and the blessings where Rivka gives to Yaakov a wool garment that belonged to Eisav so as not to get caught by Yitzchak.
In Vayeishev all of a sudden as a sign of love, Yaakov gives a coat to Yosef. Perhaps this coat is the same coat passed down from Adam Harishon?
If it's true, that the coat was given over to Yaakov when Rivka took it. How could that be? If the special powers of the garment were its aid in hunting, why didn't Eisav take it along with him, he just went out to hunt for his father so he should bless him, surely he would have brought it along?
Further, why would Yosef's brothers, who surely knew the great lineage and significance of the coat, destroy it?
