Isaiah 30:29

27 Behold, the Name of the LORD comes from afar, with burning anger and dense smoke. His lips are full of fury, and His tongue is like a consuming fire.

28 His breath is like a rushing torrent that rises to the neck. He comes to sift the nations in a sieve of destruction; He bridles the jaws of the peoples to lead them astray.

You will sing as on the night of a holy festival, and your heart will rejoice like one who walks to the music of a flute, going up to the mountain of the LORD, to the Rock of Israel.

30 And the LORD will cause His majestic voice to be heard and His mighty arm to be revealed, striking in angry wrath with a flame of consuming fire, and with cloudburst, storm, and hailstones.

31 For Assyria will be shattered at the voice of the LORD; He will strike them with His scepter.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
