'Deep Shadow' in the Bible

Let darkness and deep shadow claim it; let clouds settle on it; let them terrify it [with the] blackness of day.

Before I go--and I will not return-- to [the] land of darkness and deep shadow,

to [the] land of darkness, like [the] darkness of a deep shadow and {chaos}, so that it shines forth like darkness.'"

"He uncovers mysteries out of darkness, and he brings deep shadow to the light.

My face is red because of weeping, and deep shadows [are] on my eyelids,

He puts an end to darkness, and he searches out the farthest limits [for the] ore [in] gloom and deep shadow.

There is no darkness, and there is no deep shadow where instigators of mischief might hide themselves.

Have [the] gates of death been revealed to you? Or have you seen [the] gates of deep shadow?
