Jeremiah 4:13
Behold, he advances like the clouds, his chariots like the whirlwind. His horses are swifter than eagles. Woe to us, for we are ruined!
Ezekiel 38:9, 16
You and all your troops, and many peoples with you will go up, advancing like a thunderstorm; you will be like a cloud covering the land. / You will advance against My people Israel like a cloud covering the land. It will happen in the latter days, O Gog, that I will bring you against My land, so that the nations may know Me when I show Myself holy in you before their eyes.
