Revelation 18:19
They will throw dust on their heads, and with weeping and mourning cry out: 'Woe! Woe to the great city, where all who had ships on the sea became rich through her wealth! In one hour she has been brought to ruin!' - the gesture of throwing dust on the head (a sign of grief and humiliation) accompanies their lament. The ship-owners, who imagined their wealth secure through Babylon, watch it vanish in one hour.
