'Light' in the Bible

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?

“Though they dig into Sheol [to hide in the deepest pit],From there My hand will take them [for judgment];And though they climb up to heaven [to hide in the realm of light],From there will I bring them down [for judgment].
