Pg. 19a, beginning with the words “הזהר בּני” – “Be careful, my son…”
 See Mishlei (26; 5) for a pasuk with similar wording.
 The MaLBI”M explains this pasuk from Mishlei, as follows:
The type of fool mentioned in this pasuk is the “k’sil”. The MaLBI”M explains that the k’sil is familiar with certain aspects of wisdom, but due to his desires, he wishes to remain ignorant of a great deal of wisdom. With regards to a typical fool, who is unaware of wisdom, there is a possibility that he can become receptive to wisdom, as he doesn’t have any ulterior motives to reject that wisdom. The k’sil, however, will scorn your words of intelligence, for he willingly rejects wisdom in favor of his desires.
 The entire pasuk reads as follows:
“[When the man of] wickedness comes, disgrace comes [with him], and with those who are modest, [comes] wisdom.” (Mishlei: 11; 2)
Metzudas David explains that disgrace comes along with the man of wickedness, for he will shame people.
MaLBI”M explains that the “zade” – “wicked person” argues with truth and wisdom, intentionally transgressing truth and wisdom with contempt. Disgrace comes with such a wicked individual, for he chooses a contemptible lifestyle, in direct contrast to the honorable life of truth and wisdom.
Thus, according to Metzudas David, the wicked individual shames others, and according to the MaLBI”M, shame comes with the wicked person, for he lives a shameful.
