'Darkness' in the Bible

Then He said to me, “Son of man, do you see what the elders of the house of Israel are doing in the darkness, each at the shrine of his idol? For they are saying, ‘The Lord does not see us. The Lord has abandoned the land.’”

"While they're watching, carry your luggage on your shoulder and go out in total darkness. Cover your face so that you won't see the land, because I'm using you as a sign to Israel's house."

I did just as I was commanded. I brought out the luggage as if it were luggage for exile. I did this during the day. Then in the evening I dug a hole in the wall with my hand and brought the luggage out in total darkness and carried it out on my shoulder while they were watching.

As to the prince who is in their midst, on the shoulder he beareth in the darkness, and he goeth forth, through the wall they dig to bring forth by it, his face he covereth, that he may not look on the very surface of the land.

All the bright lights of heaven will I make dark over thee, and set darkness upon thy land, saith the Lord GOD.

As a shepherd's searching of his drove, In the day of his being in the midst of his scattered flock, so I do seek My flock, And have delivered them out of all places, Whither they have been scattered, In a day of cloud and thick darkness.
