'Day of Darkness' in the Bible

"He is wandering for bread, [saying], 'Where [is it]?' He knows that a day of darkness [is] ready {at hand}.

A day of darkness and gloom, a day of cloud and thick darkness, like the dawn spreads on the mountains, a great and strong army! There has been nothing like it from old, and after it nothing will be again {for generations to come}.

That day [will be] a day of wrath, a day of trouble and distress, a day of disaster and ruination, a day of darkness and deep gloom, a day of clouds and thick clouds,
