After describing Nineveh’s fall (Nahum 2:1–10), Nahum includes the first of three taunt songs (see also 3:8–13, 14–19). Taunt songs were a common form of poetry in the ancient Near East.
In this song, Nahum uses sharp humor to compare Nineveh to a lion’s den. Sennacherib and other Assyrian kings often compared themselves to lions. They even decorated their palaces with images of lions and scenes of royal lion hunts.
However, because God had become Nineveh’s enemy, the city would no longer be a safe place for a powerful predator. Its strength and pride would not protect it.
