תֵּ֣חַת גְּעָרָ֣ה בְמֵבִ֑ין מֵהַכּ֖וֹת כְּסִ֣יל מֵאָֽה׃
對明白人責備一句，比打愚昧人一百下更能使他折服。
Rashi
The humility caused by the rebuke of an understanding person Heb. תחת. The accent in the word תחת is above on the “tav,” unlike the rest of the Scriptures. Therefore, I say that it is a noun, like תחת and its explanation is as follows. The humility caused by a rebuke is recognizable in an understanding person more than one hundred blows that they strike the fool.
