16-17Evil people are restless
unless they're making trouble;
They can't get a good night's sleep
unless they've made life miserable for somebody.
Perversity is their food and drink,
violence their drug of choice.
18-19The ways of right-living people glow with light;
the longer they live, the brighter they shine.
But the road of wrongdoing gets darker and darker—
travelers can't see a thing; they fall flat on their faces.
