What do we learn from "Malchei Tzevakos Yidodun Yidodun"?
Rashi (Shemos 20:15, from Shabbos 88b): After every utterance of Hashem, Yisrael retreated 12 Mil, and angels 1 nudged them back. We read Yidodun like 'Yedadun'.
Rashi: The nations will be cast out of Eretz Yisrael.
Radak: The kings of the legions who camped against Yerushalayim will flee from Yisrael.
Malbim: The kings of the legions who camped against Yerushalayim will go away one by one.
Rashi (36): This is difficult. "Malchei" are kings. Angels are called Mal'achei with an Aleph!
What is the meaning of "u'Nevas Bayis Techalek Shalal"?
Rashi: Keneses Yisrael, the mistress of this residence, will divide the spoils [Radak - of their enemies] - "v'Hayah Sachrah v'Esnanah Kodesh" (Yeshayah 23:18).
