'Light' in the Bible

And the path of the righteous is as a shining light, Going and brightening till the day is established,

For a lamp is the command, And the law a light, And a way of life are reproofs of instruction,

The light of the righteous rejoiceth, And the lamp of the wicked is extinguished.

The light of the eyes rejoiceth the heart, A good report maketh fat the bone.

In the light of a king's face is life, And his good-will is as a cloud of the latter rain.

Whoso is saluting his friend with a loud voice, In the morning rising early, A light thing it is reckoned to him.
