오바댜 1:18의 Chasidut

Genesis 32:4: "Yaakov sent angels"-- Rashi explains that the word "angel" [in context] means just that: an angel [whereas other commentaries could interpret the word as "messenger"). It's known from the Zohar that every mitzvah creates an angel. The main antagonism to the angelic minister of Eisav is saying the prayer of Shema. This is the meaning of the verse: "the house of Yaakov is fire, the house of Eisav is straw" (Ovadia 1:18) -- "straw" is an acronym is for "kriat shema" [the prayer of Shema]. The Shema directly opposes Eisav. As it says Megaleh Amukot, "so shall say you to my master Esiav" -- "so" refers to recital of Shema. The word "mamish" [used by Rashi in his commentary] stands for "mekabalet malchus shamayim" (accepting the yoke of heaven), referring to the angels emerging from the intent of our Shema. This is the main antagonism to subjugate the angelic minister of Eisav. Eisav also includes the seed of Amalek, and the Torah says that Hashem's name is not complete until Amalek is eradicated. On that day, when the saviors go to the mountain of Zion to judge the mountain of Eisav, dominion will belong to G-d, and on that day Hashem will be one and His Name will be one.
