'Dark' in the Bible

And he said unto me, Hast thou seen, son of man, what the elders of the house of Israel do in the dark, every one in his chambers of imagery? for they say, Jehovah seeth us not; Jehovah hath forsaken the land.

In their sight shalt thou bear it upon thy shoulder, and carry it forth in the dark; thou shalt cover thy face, and thou shalt not see the ground: for I have appointed thee for a sign unto the house of Israel.

And I did so as I was commanded: I brought forth my baggage by day, as a captive's baggage, and in the even I digged through the wall with my hand; I brought it forth in the dark, and bore it upon my shoulder, in their sight.

And the prince that is among them shall bear upon his shoulder in the dark, and shall go forth; they shall dig through the wall to carry out thereby; he shall cover his face, that he see not the land with his eyes.

As a shepherd tendeth his flock in the day that he is among his scattered sheep, so will I tend my sheep, and will deliver them out of all places whither they have been scattered in the cloudy and dark day.
