Proverbs 21:11-13

Amplified Bible

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.^(A)
12 
The righteous one keeps an eye on the house of the wicked—
How the wicked are cast down to ruin.
¹³ 
Whoever shuts his ears at the cry of the poor
Will cry out himself and not be answered.^(B)
