Nahum 2:7

The Lord’s judgment of Nineveh had been determined. The city would be stripped of her treasures and they and their possessors would be carried off to other places. Even the slave girls, the bottom of the social scale, as well as the nobles (Nahum 2:5), the top, would lament the fall of the city. They would make mournful sounds and beat their breasts like doves that cooed and flapped their wings. Normally one would expect slaves in a city to rejoice at its destruction since that would mean their liberation. But life in Nineveh was good for some foreigners taken there as captives.
