'Light' in the Bible

he revealeth the deep and secret things; he knoweth what is in the darkness, and the light dwelleth with him.

There is a man in thy kingdom, in whom is the spirit of the holy gods; and in the days of thy father light and understanding and wisdom, like the wisdom of the gods, were found in him; and the king Nebuchadnezzar thy father, the king, I say , thy father, made him master of the magicians, enchanters, Chaldeans, and soothsayers;

I have heard of thee, that the spirit of the gods is in thee, and that light and understanding and excellent wisdom are found in thee.
