Proverbs 21:10-12

Amplified Bible

¹⁰ 
The soul of the wicked desires evil [like an addictive substance];
His neighbor finds no compassion in his eyes.^(A)
11 
When the scoffer is punished, the naive [observes the lesson and] becomes wise;
But when the wise and teachable person is instructed, he receives knowledge.^(B)
12 
The righteous one keeps an eye on the house of the wicked—
How the wicked are cast down to ruin.
