The book of Nahum is believed to have been written around 660 BCE in Jerusalem by a skilled royal scribe using the pseudonym Nahum. This name was chosen to inspire the people of Judah, who were suffering under Assyrian rule. Drawing from the works of Isaiah and the Psalms, which he likely encountered in the temple, the scribe crafted a message predicting the fall of the Assyrian empire, symbolized by Nineveh. His knowledge of Assyrian texts, like vassal treaties and royal annals, helped him articulate this prophecy. When Nineveh fell in 612 BCE, Nahum's book gained popularity as a testament to true prophecy. It influenced other prophets, such as Habakkuk and those during the Babylonian exile, like the Second Isaiah and Jeremiah. Its impact is also seen in the writings of the Qumran community and the New Testament.
