טוֹבָ֥ה חָכְמָ֖ה מִכְּלֵ֣י קְרָ֑ב וְחוֹטֶ֣א אֶחָ֔ד יְאַבֵּ֥ד טוֹבָ֥ה הַרְבֵּֽה׃
Mieux vaut la sagesse que des engins de guerre; mais un seul pécheur gâte beaucoup de bien.
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.”
