The light of the righteous rejoiceth: but the lamp of the wicked shall be put out.
The light of the righteous rejoiceth - joyfully shines forth. "The light of the righteous" is that of their piety, joy, peace, and blessedness, which, beginning here, is perfected in the life to come (Matthew 5:16; Psalms 97:11; Psalms 112:4; Proverbs 4:18). It is like the sun, ever brightening from morning to mid-day.
But the lamp of the wicked shall be put out. The little and faint spark of prosperity which the wicked have now, shall be put out, as a "lamp" which soon goes out; whereas the righteous shine like the sunlight, permanently and universally (Job 18:5; Job 21:17).
