'Light' in the Bible

But the path of the righteous is as the dawning 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 good tidings make the bones fat.

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