מוסר אויף מלכים ב 24:14

The Torah (19,14) continues with: "Do not curse the deaf." This should be understood in the sense of Kings II 24,14: וכל החרש והמסגר, "all the craftsmen and smiths." In the above mentioned context all the leading people of Jerusalem who could have enabled its continued existence as an independent nation were exiled. Here, too, the Torah means that one should not curse the judges, the leaders, etc., without whom the state could not continue to function properly.
