'Lamp' in the Bible

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.

Whoso curseth his father or his mother, his lamp shall be put out in the blackest darkness.

Man's spirit is the lamp of Jehovah, searching all the inner parts of the belly.

Lofty eyes, and a proud heart, the lamp of the wicked, is sin.

for there shall be no future to the evil man; the lamp of the wicked shall be put out.

She perceiveth that her earning is good; her lamp goeth not out by night.
