'Light' in the Bible

But the path of the righteous is as the shining light, going on and brightening until the day be fully come.

For the commandment is a lamp, and the teaching a 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.

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