'Daylight' in the Bible

They will roar over it at that time, like the sea waves roar. If one surveys the land, watch out! There's darkness and distress; even the daylight is darkened by its clouds.

We go on our way, like blind men feeling for the wall, even like those who have no eyes: we are running against things in daylight as if it was evening; our place is in the dark like dead men.
