איוב, פרק כ״ט, פסוק ט׳

The presence of a truly great leader can inspire such deep awe that it instantly silences even those who hold power and authority. Typically, princes and rulers are people whose natural role is to speak, command, and give orders. Yet, when Job appeared, these powerful figures completely restrained themselves from speaking [מצודת ציון]. This was not merely a general quiet. It was a sudden, sharp interruption. Leaders who were right in the middle of a conversation would stop immediately, leaving their sentences unfinished the moment Job arrived [מצודת דוד, אלשיך].

There are complementary reasons for this profound silence. On one hand, Job instantly assumed the role of the ultimate authority, taking over the position of command in their place [מלבי״ם]. At the same time, their silence was born out of deep respect and eager anticipation, as they waited attentively for Job to be the first to speak [רש״י].

To express their absolute submission, they would physically place the palms of their hands over their mouths [מצודת ציון, ביאור שטיינזלץ]. This action served as a clear physical sign of their silence, ensuring their mouths remained shut and guaranteeing they would not speak another word in his presence [מצודת דוד, ביאור שטיינזלץ].
