Nahum 3:6

And I will cast abominable filth upon thee, and make thee vile, and will set thee as a gazingstock.

Nahum 3:1-7 is the record of the final destruction of Nineveh. God had threatened Nineveh with destruction, yet its inhabitants repented and the threatened destruction was averted. Afterward they turned back to idolatry, their sins reached to heaven, and their destruction came.
