The light of the righteous rejoiceth: but the lamp of the wicked shall be put out.
– Proverbs 13:9
The course a person is on in life gives an expectation for their end. We might say the righteous have a bright future. The word for rejoiceth can include the idea of brightening. They are in the way of increasing light (Proverbs 4:18). The lamp being put out refers to darkness and to death. The image is a repeated warning (Proverbs 20:20; 24:20). Whatever brightness the wicked enjoy in life will be turned to darkness when their expectation dies (Proverbs 11:7).
