'Lamp' in the Bible

Because the command is a lamp and the Law a light, rebukes that discipline are a way of life

The light of the righteous shines, but the lamp of the wicked is extinguished.

Whoever curses his father or mother, his lamp will be extinguished in the deepest darkness.

A person's spirit is the lamp of the LORD; it searches throughout one's innermost being.

For the wicked man has no future; the lamp of the wicked will be extinguished.

She is confident that her profits are sufficient. Her lamp does not go out at night.
