Zephaniah 3:1

Woe to her that is filthy and polluted, to the oppressing city!

Woe falls upon a city defined by moral filthiness, spiritual pollution, and a practice of oppression. Filth denotes its inward corruption, pollution its defilement before God, and oppression its cruel exercise of power over others. That threefold character is not confined to ancient times but describes the condition of the world in the last days.
