'Dark' in the Bible

For a day of dark and deep shade is near, a day of cloud and black night: like a black cloud a great and strong people is covering the mountains; there has never been any like them and will not be after them again, from generation to generation.

The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:

The sun will be made dark and the moon turned to blood, before the great day of the Lord comes, a day to be feared.

The sun and moon will grow dark,and the stars will cease their shining.
