איוב, פרק ב׳, פסוק ז׳

Immediately after leaving the presence of God, the Satan inflicts a severe, highly calculated physical blow upon Job. This departure is driven by one clear purpose: to strike the man down [מצודת דוד].

The affliction chosen is a harsh skin disease [ביאור שטיינזלץ]. It manifests as severe blisters that erupt and burst on their own, leaving behind burning crusts. This causes an intense, relentless itch, much like the severe rashes seen in certain childhood illnesses [תקות אנוש]. The condition brings extreme physical agony [מצודת דוד]. Beyond the bodily pain, the illness carries a devastating social and psychological weight. The outward appearance of the disease repulses others, forcing the sufferer into isolation. Consequently, Job is left not only in physical torment but also deeply miserable, lonely, and despised by his surroundings [ביאור שטיינזלץ].

Out of all possible ailments, the selection of this specific disease is highly intentional. Unlike conditions that might paralyze a person or take away their ability to speak, this skin affliction leaves the voice completely intact. In fact, people suffering from this type of irritating condition often talk extensively with others, using conversation as a distraction to find some small relief from their pain [תקות אנוש].

The devastation to Job's body is absolute, covering every inch of his skin [מצודת דוד]. The outbreak begins at the very bottom of his feet and spreads all the way up to the crown of his head, right at the center where the hair parts [מצודת ציון].

On a hidden, spiritual level, Kabbalistic traditions explain that this terrible suffering is not a random occurrence. Instead, it serves as a process of spiritual cleansing. According to this perspective, Job is enduring these trials to repair his soul, as he is understood to be a reincarnation of Terah, the father of Abraham. The painful disease acts as a means to cleanse and atone for the lingering sins of his past lives [חומת אנך].
