The Lord Is a Jealous and Avenging God

In the most literal sense, then, Nahum's book is dedicated to predicting the complete ruinous destruction of Nineveh at the hands of the Babylonians. That did happen in 612 BC. The Lord is a jealous and avenging God. The Lord takes vengeance and is filled with wrath. He will not leave the guilty unpunished. His way is in the whirlwind and the storm and clouds are the dust of his feet; you, Nineveh, are about to reap the whirlwind.
