Komentarz do Koheleta 7:7

For quarreling makes the wise foolish. When the fool provokes the wise person, he confuses his thoughts, and he too, stumbles. Dasan and Aviram taunted Moshe, by saying, “may Adonoy look down upon you and judge, etc.,”¹⁹Shemos 5:21. and they confused him and caused his wisdom to depart and to speak in anger²⁰A wise person should distance himself from being involved in discussion with fools because it will cause his own wisdom to suffer. (Metsudas Dovid) against the Holy One, Blessed Is He, and he said, “and You did not save Your people,”²¹Ibid. Verse 23. and he was punished for this matter, when He replied to him, “now you will see,”²²Ibid. 6:1. but you will not see the war of the thirty-one kings.

“For exploitation disconcerts a wise man, and destroys the gift of understanding” (Ecclesiastes 7:7).
“For exploitation [haoshek] disconcerts a wise man” – disputes [esek] in which Torah scholars are engaged, with each other, “disconcerts a wise man” – it confuses one’s wisdom.
“And destroys the gift of understanding” – Rabbi Yehoshua ben Levi said: I learned eighty halakhot from Yehuda Ben Pedaya regarding the plowing of a grave, but because I was engaged [asuk] in the needs of the masses, I forgot them. Who is a Torah scholar? Rabbi Abbahu [said] in the name of Rabbi Yoḥanan: Anyone who cancels his engagements for the sake of his studies. It is taught: Anyone whom, when they ask him about a halakha from his studies, he provides an answer.

And a gift [corrupts] the heart. The heart of wisdom, which is a gift to man,²³I.e., the provocation by the wicked, causes the wise to forfeit their wisdom, which is God‘s gift to man. as it is stated, “For Adonoy gives wisdom.”²⁴Mishlei 2:6.
