'Cloud' in the Bible

O Ephraim, what shall I do unto thee? O Judah, what shall I do unto thee? for your goodness is as a morning cloud, and as the dew that goeth early away.

Therefore they shall be as the morning cloud, and as the dew that passeth early away, as the chaff that is driven with the whirlwind out of the threshing-floor, and as the smoke out of the chimney.
