Left vs. Right and Binyamin's Role
The following was based on the נזה"ק על ב"ר פ' עג אות ה
|Mashiah Ben Yosef||Mashiah Ben David|
Mashiah Ben Yosef will rule over Eisav, while Mashiah Ben David will rule over Yishmael.
How about Binyamin?
On the one hand, he's from Rahel, and is destined to destroy Eisav, as Binyamin is the tribe that twice won over Amalek. (He is not as powerful as Yosef for ruling over Eisav though.)
On the other hand, however, Binyamin pretty much clung to Yehuda when the 10 tribes split off. Also, he was called בן ימין for a reason. (Also, Yaakov Avinu was able to confront Eisav without Binyamin.)
Really, Binyamin is a mixture of both. He's part of the left, but has a foothold in the right.
(Also, see this Ge'ulah Perspectives post which suggests that Sha'ul could have been MBY had he not kept Agag alive.)
Any comparisons to Binyamin Netanyahu and his fateful mission of destroying the Amalek of our time who is clothed in Yishmael are purely coincidental. ;-)
