Musar su Lamentazioni 3:28

If he is in a country whose leaders are bad, and whose people do not walk in the righteous path, he should go to a place whose people are righteous and follow good ways. And if all the countries of which he knows and hears conduct themselves in a way that is not good, or if he cannot go to a country whose leaders are good, because of mobilization of troops or because of illness, then let him sit by himself alone, as it is said, "Let him sit alone and keep silence" (Lam. 3:28). And if the people among whom he dwells are so evil and such sinners that they do not permit him to dwell in that country unless he mingles with them and conducts himself in their evil way, then he should go forth to caves, ravines and deserts, but let him not conduct himself in the way of the sinners. As it is said, "Oh that I were in the wilderness, in a lodging-place of wayfaring men" (Jer. 9:1).
