The destruction of the Assyrian empire is an image of how God will confront and bring down all violent human empires. This is about God’s commitment to justice, which is as true today as it was in the time of Nahum. While God will defeat human evil, he does not forget the innocent. He promises to provide a refuge on the day of judgment for anyone who humbles themselves before God.
The book of Nahum is a collection of poems announcing the downfall of some of Israel's worst oppressors. Referencing Daniel, Exodus, and Isaiah, Nahum shows us that the destruction of Nineveh and Assyria are examples of how God works in history in every age.
