“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.
