The
eigth king of Edom is Hadar (Bereshit 36:39). The Torah introduces also his wife, Mehetabel. The Pasuk hints at an essential change of reality, akin to a phase transition in physics. With the death of the seventh king, the power of Edom breaks down. Correspondingly, the Sitra Achra can no longer intervene between HaShem and Israel. Hadar and Mehetabel refer to the unison of HaShem and Israel. But Hadar also refers to Hadrian. The secret is that in view of the loss of power over Israel, and over the Land of Israel, the eigth king of Edom will entice and tease Israel as Hadrian did, with
trickery.
זמין קודשא בריך הוא לאחייא לכל אינון מלכין דעקו לישראל ולירושלם, לאנדריאנוס ללופינוס ונבוכדנצר ולסנחריב
In the future, HaKadosh Baruch Hu will resurrect all those kings who afflicted Israel and Jerusalem, Andrianus (Hadrian), Lupinus, Nevuchadnezar, and Sancheriv (Zohar, Beshalach, 58b).
