“With denunciation you went marching through the earth. In anger you went threshing the nations.

Hab. 3:12,

In order not to let the godless nations succeed in their wicked purpose, Jehovah will have to go forth for the salvation of his people. So, in “denunciation” of the evil-intentioned nations, he will march through the earth and angrily thresh the nations, pounding them underfoot like grain on a threshing floor.
