'Day of Darkness' in the Bible

He wandereth abroad for bread,'saying , Where is it? He knoweth that the day of darkness is ready at his hand.

a day of darkness and gloominess, a day of clouds and thick darkness, as the dawn spread upon the mountains; a great people and a strong; there hath not been ever the like, neither shall be any more after them, even to the years of many generations.

That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness,
