A profound sense of social humiliation and alienation often accompanies severe physical and mental decline. The primary approach among commentators is that the enemies harbor deep contempt and mockery for the sufferer because of his weakness, poverty, and gaunt appearance. This extreme thinness is the direct result of his frequent fasting [מצודת דוד]. Upon seeing his suffering, these enemies respond with a distinct physical gesture: they shake their heads. This movement serves as a clear expression of disrespect and mockery.
Beyond the basic understanding of this gesture, there are deeper perspectives on what this silent movement represents. Some view it as a mark of how far the enemies' hostility has escalated. Initially, they would actively mock him with harsh words. However, as his body withered and his status plummeted in their eyes, they stopped bothering to even speak to him. Instead, they reduced their cruelty to a silent, dismissive shake of the head, signaling absolute contempt [אלשיך].
Another perspective suggests that this mocking gesture is not merely a reaction to his frail appearance. Rather, it is a resentful response to his refusal to follow their ways or seek honor in their social circles. Alongside this, the head shake may simply be an automatic reaction of disgust that overtakes them whenever they happen to cross his path [המאירי].
