'Day of Darkness' in the Bible

He wanders for bread, saying, Where is it? He knows that the day of darkness is ready at hand.

a day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread on the mountains; a great people and a strong people; there has not been ever the like, nor shall there ever be again, even to the years of many generations.

That day is a day of wrath, a day of trouble and distress, a day of waste and ruin, a day of darkness and gloominess, a day of clouds and thick darkness,
