Nahum mentioned the fall of the Egyptian city of Thebes (3:8), so we know he wrote after that event, which took place in 663 B.C. The Assyrian king Ashurbanipal conquered it. The prophet predicted the fall of the Assyrian capital, Nineveh, which happened in 612 B.C., so he must have written this book between 663 and 612 B.C. Nineveh fell to a combined force of Medes, Babylonians, and Scythians.3
There is some evidence that points to Nahum writing shortly after Thebes fell. First, Nahum's description of Nineveh (1:12; 3:1, 4, 16) does not fit the city as it existed between 626 and 612 B.C. when Ashurbanipal's sons, Ashur-etil-ilani (626-623 B.C.) and Sin-shar-ishkun (623-612 B.C.), ruled over it. Second, the Southern Kingdom of Judah was under the yoke of Assyria when Nahum wrote (1:13, 15; 2:1, 3), a condition that marked the reign of Manasseh (697-642 B.C.) more than that of Josiah (640-609 B.C.). Third, if Nahum wrote after 654 B.C., his rhetorical question in 3:8 would have had little or no force since Thebes rose to power again in that year.4Thus a date of composition between 660 and 650 B.C. seems most likely.
