'Clouds' in the Bible

The Lord is slow to get angry and great in power, and will not let the sinner go without punishment: the way of the Lord is in the wind and the storm, and the clouds are the dust of his feet.

Your crowned ones are like the locusts, and your scribes like the clouds of insects which take cover in the walls on a cold day, but when the sun comes up they go in flight, and are seen no longer in their place.
