Why did God choose Avraham? The midrash offers two explanations. The story of the furnace parallels the story of Chanania, Mishael and Azaria, and the story about destroying the idols is taken from Gideon. The two parallels points to a broader connection between Avraham and these characters, and about the sin of Nimrod and The Generation of Disunity (Dor Hapalaga).
