On the popular Blog of Rabbi Lazar Brody the following noteworthy posting appeared:
In a recent lecture, Rav Moshe Wolfson shlit’a, the esteemed mashgiach (spiritual Dean) of Yeshivat Torah V’Daas said that the fall of a nation is preceded by the fall of it’s sar, or administering angel. Once the sar falls, then the nation will fall. This is based on the Zohar (section 2, page 18a – LB) which says that what the Jews saw on the banks of the Red Sea suf was the sar of Egypt dying. Yishmael has 12 sarim (plural for “sar”).
Rav Wolfson was also quoted as saying (on Monday after morning prayers), “Osama bin Ladin, being the biggest danger to the entire world, had the biggest sar of Yishmael. During these past few weeks as we saw so many entrenched arab leaders, heirs of Yishmael, fall, it is apparent that their defending sar has already fallen and they will continue their downfalls. It is a great thing when sarim fall. The Princes of Yishmael are falling. Bin Laden had their biggest sar. The way the Maharal puts it, he does not have to be a direct descendant of Yishmael. Bin Laden is from the culture of Yishmael.”
