טוֹבָ֥ה חָכְמָ֖ה מִכְּלֵ֣י קְרָ֑ב וְחוֹטֶ֣א אֶחָ֔ד יְאַבֵּ֥ד טוֹבָ֥ה הַרְבֵּֽה׃
智慧勝過打仗的兵器；但一個罪人能敗壞許多的好處。
Rashi
but a man of evil devices will condemn One who has evil devices will condemn. He will condemn the people to bring evil [upon them], and so he states (Ecc. 9:18): “but one sinner destroys much good.”
