'Cloud' in the Bible

O Ephraim, what am I to do to you? O Judah, what am I to do to you? For your love is like a morning cloud, and like the dew which goes early away.

So they will be like the morning cloud, like the dew which goes early away, like the dust of the grain which the wind is driving out of the crushing-floor, like smoke going up from the fireplace.
