'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 is troubled before them and the heavens are shaking: the sun and the moon have become dark, and the stars keep back 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 the moon have become dark, and the stars keep back their shining.
