'Light' in the Bible

“It is He who reveals the profound and hidden things;He knows what is in the darkness,And the light dwells with Him.

Suddenly the fingers of a man’s hand appeared and began writing opposite the lampstand on [a well-lit area of] the plaster of the wall of the king’s palace, and the king saw the part of the hand that did the writing.

There is a man in your kingdom in whom is a spirit of the holy gods; and in the days of your father, illumination, understanding and wisdom like the wisdom of the gods were found in him. And King Nebuchadnezzar, your father—your father the king, appointed him chief of the magicians, enchanters, Chaldeans and diviners.

I have heard of you, that a spirit of the gods is in you, and that illumination, insight, and extraordinary wisdom have been found in you.

Those who are [spiritually] wise will shine brightly like the brightness of the expanse of heaven, and those who lead many to righteousness, [will shine] like the stars forever and ever.
