Musar untuk Amsal 24:1

This is one of the things for which a person becomes obligated to leave the group of evildoers. For he will be punished for hearing their evil words and being too listless to answer them. And this is something explicit in the words of Solomon, as it is stated (Proverbs 24:1-2), “Do not envy evil men; do not desire to be with them. For their hearts talk violence, and their lips speak mischief.” And he meant to say [it is] because you will bear the iniquity when they sin. For you will constantly hear their evil words and you will be silent.

And, in truth, one who has an understanding heart, should flee the company of "street-corner men" as one flees fire. For why should he enter the company of men whom he will afterwards be obligated to reprove for their forbidden speech? For if he heard their words and neglects to rebut them, he, too, will be punished, as it is written in Sha’arei Teshuvah 197: If a man hears others speaking lashon hara or he hears "all mouths speaking foulness," or he sits in the midst of scoffers, who shame Torah and mitzvoth, and knowing them to be "defiers and despisers," who, if he reproves them, will not heed his words, wherefore, he puts his "hand to his mouth" — he, too, will be punished. For he will not have answered "the fools according to their folly," so that men may come to say of him that he, too, is like them and acquiesces in their words. How much more so is he obligated to answer and rebuke them to accord honor to the Torah and the mitzvoth which they have scorned and scoffed at, and to be jealous of the honor of the clean and the righteous whom they have spoken against. This is one of the reasons for which it is incumbent upon a man to leave the company of the wicked; for he will be punished for hearing their evil words and refraining from answering them. And this is explicitly stated by Solomon (viz. Proverbs 24:1-2)."
