Musar zu Mischlej 18:3

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).

Just as contempt is associated with the wicked, as in the verse we mentioned earlier "When a wicked man comes, there also comes contempt" (Mishlei 18:3), so is honor associated with the righteous. For honor resides with them and does not separate from them, and it is written: "and before his elders there is honor"(Isaiah 24:23).

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).

We have already seen that Moses, the greatest man that ever lived, was also the most humble.

You can see clearly that most high officials and kings or other people in positions of power, regardless of their rank, stumble and become corrupted by the flattery of their subordinates.
