Musar su Geremia 4:22

And the third is wealth acquired and held as an act of vengeance. And the sign of this is that the owner of the money harms others with his wealth and boasts of it, and does not give charity, and is fully occupied with enjoying it as it is written: "And behold joy and gladness, slaying oxen and killing sheep" (Is. 22:13), and it says further: "And the harp and the psaltery, the tabret and the pipe, and wine are in their feasts" (Ibid. 5:12). And he does not pay of all his wealth that which is due to the Holy One, Blessed be He. On this it is said: "Riches kept by the owner thereof to his hurt" (Eccl. 5:12). And thus it is with the wise when he schemes to do evil deeds and not good deeds with his wisdom, as it is said: "They are wise to do evil, but to do good they have no knowledge" (Jer. 4:22). Then his wisdom is a stumbling block to him.

Therefore, the intelligent person will do with his wealth and his wisdom the good he can, according to the extent of his wealth and wisdom, and will add to his modesty and humility and his heart will not grow haughty and he will always worry whether this wealth is not his sole reward. Such a person belongs to those who fear that their wealth may destroy them and of whom it is said: "But who instantly requites with distraction those who reject him" (Deut. 7:10). The wise man, too, will worry whether he is among those of whom it is said: "They are wise to do evil and do not know how to do good" (Jer. 4:22). And every man is obligated to grow wiser and to understand more clearly and continue to attain through his wisdom good deeds until his wisdom can achieve no more.
