And I gave Mount Seir to Esau: Onkeles, the Aramaic translation, interprets Har Seir as the Har Sheidin, a Mountain of Demons, based on the verse, "And there shall satyrs dance." (Is. 13:21) Mount Seir is the portion of Samael, who has a mighty storm (saar) in his heart, as it is written, "My Lord shall sound the ram's horn and advance in a stormy tempest." (Zach. 9:14) He is from the side of redness (evil) and therefore Esau is called Edom. Jacob, on the other hand, was smooth, the opposite of a man of Seir (hairy). He is stands apart and separated from the tempest and the bonds (of Seir). Therefore his image is on the throne of glory. He and his offspring went down to Egypt to pay the debt that was decreed at the Covenant of the Pieces (Gen. 15).
