Nahum prophesied the destruction of Nineveh, the capital of Assyria, between 663-612 BC. [1] Nahum focused on delivering God's message of judgment against Nineveh for their cruelty and arrogance in thinking their power was their own rather than from God. [2] Nahum's prophecies were fulfilled when Nineveh was destroyed in 612 BC, ending Assyria's oppression of Judah and demonstrating God's faithfulness to protect His people. [3] The book highlights God's sovereignty, power as a divine warrior, and role as righteous judge against those who act against Him or mistreat His people.
