Musar su Proverbi 11:12

In one's speaking: our sages, of blessed memory, said: "one should always speak with other people in a gentle manner" (Yomah 86a). This is stated explicitly in scripture: "the words of the wise are heeded [when spoken] gently" (Kohelet 9:17). One's words should be of honoring [others] not of belittling them. Likewise scripture says: "he who belittles his fellow lacks sense" (Mishlei 11:12), and "when the wicked comes, there also comes contempt" (Mishlei 18:3).

And when a man contemplates further on his obligation to G-d, blessed be He, and to what extent it is neglected by him and how much he is lax in it, certainly he will feel shame and not arrogance, humiliation and not elevation of heart. Likewise scripture says: "I have indeed heard Ephraim grieving... for after my repentance I have regretted; and after I realized, I smote my thigh; I felt ashamed and disgraced" (Yirmiyahu 31:17-18).

Above all, one should always contemplate to recognize the weakness of human intellect and its great many errors and falsehoods, how it is always nearer to error than true knowledge. Therefore, he should always fear this danger, and seek to learn from every person, always listening to advice, lest he stumble. This is what our sages, of blessed memory, said: "Who is wise? He who learns from all men" (Avot 4:1), and scripture says "he who hearkens to counsel is wise" (Mishlei 12:15).
