'Lamp' in the Bible

For the commandment is a lamp, and the law is light. Reproofs of instruction are the way of life,

The light of the righteous shines brightly, but the lamp of the wicked is snuffed out.

Whoever curses his father or his mother, his lamp shall be put out in blackness of darkness.

The spirit of man is Yahweh's lamp, searching all his innermost parts.

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

for there will be no reward to the evil man; and the lamp of the wicked shall be snuffed out.

She perceives that her merchandise is profitable. Her lamp doesn't go out by night.
