'Cloud' in the Bible

Let darkness and the deepest shadow claim it; let a cloud settle on it; let whatever blackens the day terrify it!

As a cloud is dispersed and then disappears, so the one who goes down to the grave does not come up again.

Terrors are turned loose on me; they drive away my honor like the wind, and like a cloud my deliverance has passed away.

Do you know how God commands them, how he makes lightning flash in his storm cloud?
