'Day of Darkness' in the Bible

“He wanders about for food, saying, ‘Where is it?’He knows that a day of darkness is at hand.

A day of darkness and gloom,A day of clouds and thick darkness.As the dawn is spread over the mountains,So there is a great and mighty people;There has never been anything like it,Nor will there be again after itTo the years of many generations.

A day of wrath is that day,A day of trouble and distress,A day of destruction and desolation,A day of darkness and gloom,A day of clouds and thick darkness,
