Talmud sur Les Proverbes 5:22

(Yehoshua ben Prachya and) Nittai the Arbelite would say: Stay away from a bad neighbor, do not befriend the wicked, and do not think there is no punishment.

Stay away from a bad neighbor. Whether a neighbor in your house, a neighbor outside, or a neighbor in the field. (This teaches us) that afflictions come only [upon the house of the wicked, as it says (Proverbs 5:22), “A wicked person will be trapped by his sins.” This teaches us that] afflictions come only for the sins of the wicked. But the sins of the wicked cause him to knock down the wall of the righteous. [How so?] If there is a wall between a wicked person and a righteous person, and an infestation appears in the house of the wicked one [on the wall that stands between him and the righteous one, they will end up knocking down the wall] of the righteous one for the sins of the wicked. (Rabbi Yishmael the son of Rabbi Yohanan ben Beroka would say:) Woe to the wicked, and woe to his neighbor (for the sins of the wicked cause them to knock down the wall of the righteous).
