Book of Nahum in Wikipedia
The book of Nahum is a book in the Hebrew Bible. It stands
seventh in order among what are known as the twelve Minor
Prophets. Nahum prophesied, according to some, in the
beginning of the reign of Ahaz (740s BC). Others, however,
think that his prophecies are to be referred to the latter
half of the reign of Hezekiah (700s BC). Probably the book was
written in Jerusalem, where he witnessed the invasion of
Sennacherib and the destruction of his host (2 Kings 19:35).
And still others support the idea that the "book of vision"
was written shortly before the fall of Nineveh (612 BCE). This
theory is evidenced by the fact that the oracles must be dated
after the Assyrian destruction of Thebes in 663 BCE as this
event is mentioned in Nah 3:8...
