The relatively obscure prophecy found in Obadiah focuses primarily on the judgment of Edom. What is the theological significance of this particular prophetic focus?

A Edom's judgment serves as a warning to Israel about the dangers of intermarriage with foreign nations and the corruption of their religious practices. B Edom represents a pattern of familial betrayal and opposition to God's people, symbolizing the ultimate fate of those who reject God's covenant. C Edom's destruction is prophesied to make way for Israel's expansion and dominance over the region, fulfilling promises of territorial inheritance. D Edom's fate is linked to the cosmic battle between good and evil, where their downfall signifies the ultimate triumph of God's kingdom over the forces of chaos.
