'Lamp' in the Bible

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.

Whoso curseth his father or his mother, His lamp shall be put out in blackness of darkness.

The spirit of man is the lamp of Jehovah, Searching all his innermost parts.

A high look, and a proud heart, Even the lamp of the wicked, is sin.

For there shall be no reward to the evil man; The lamp of the wicked shall be put out.

She perceiveth that her merchandise is profitable: Her lamp goeth not out by night.
