'Light' in the Bible

But the path of the just is as the shining light, that shineth more and more unto the perfect day.

For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:

The light of the righteous rejoiceth: but the lamp of the wicked shall be put out.

The light of the eyes rejoiceth the heart: and a good report maketh the bones fat.

In the light of the king's countenance is life; and his favour is as a cloud of the latter rain.
