'Darkness' in the Bible

For behold, He who forms the mountains and creates the windAnd declares to man what are His thoughts,He who makes the dawn into darknessAnd treads on the heights of the earth—The Lord God of hosts is His name.

He who made the [cluster of stars called] Pleiades and [the constellation] Orion,Who turns deep darkness into the morningAnd darkens the day into night,Who calls for the waters of the seaAnd pours them out on the surface of the earth,The Lord is His name.

Woe (judgment is coming) to you who desire the day of the Lord [expecting rescue from the Gentiles]!Why would you want the day of the Lord?It is darkness (judgment) and not light [and rescue and prosperity];

Will not the day of the Lord be darkness, instead of light,Even very dark with no brightness in it?
