The Book of Nahum was written sometime between 663 B.C. and 612 B.C. This dating is based on the mention of the fall of Thebes (No Amon) in Egypt, which occurred around 663 B.C. and is referred to in the past tense, while the fall of Nineveh, the capital of Assyria, is predicted as a future event, with the city falling in 612 B.C. Therefore, Nahum's prophecy was composed during that period, likely before the destruction of Nineveh.
