Look! It’s 9:13 on 9/13/13. That means…absolutely nothing.
Proverbs 13:9 should be read seeing the contrast between a natural “light” for the righteous and an artificial “lamp” for the wicked. One is lasting—Let there be light!—while the other requires fuel and eventually will give out.
Proverbs 13:19 feels disjointed, but one thing to contemplate: the righteous have their desire realized, but the wicked just keep doing evil. The righteous follow God and settle in, while the wicked do no such thing.
