'Obscurity' in the Bible

In that day, the deaf will hear the words of the book, and the eyes of the blind will see out of obscurity and out of darkness.

and if you draw out your soul to the hungry, and satisfy the afflicted soul: then your light shall rise in darkness, and your obscurity be as the noonday;

Therefore is justice far from us, neither does righteousness overtake us: we look for light, but, behold, darkness; for brightness, but we walk in obscurity.
