תהלים, פרק ק״ז, פסוק י״ז

Physical suffering and illness do not occur in a vacuum. Often, they serve as a profound spiritual wake-up call. The third group of people required to express gratitude to God consists of those who have recovered from severe sickness, as their physical distress stems directly from their own actions and spiritual state [רש״י, מצודת דוד, שטיינזלץ].

The individuals who bring such suffering upon themselves act out of foolishness, though commentators offer different perspectives on the nature of this folly. A person who sins is ultimately acting foolishly, even if they possess natural wisdom [אבן עזרא]. Others view these individuals as skeptics who mistakenly attribute the events of their lives to random chance rather than God's guiding providence [מלבי״ם]. Alternatively, this foolishness describes those who have sinned so frequently that a spirit of folly has become ingrained in them as second nature [אלשיך].

The root of their affliction can be traced to two distinct paths of wrongdoing. The first is conscious rebellion, representing a deliberate revolt or a deeply ingrained habit of sin that blocks a person from accepting moral guidance. The second is rooted in a distorted intellect and heresy [מלבי״ם]. Because they walk down these paths, they are subjected to the severe pain and agony of disease [רש״י, מצודת דוד, שטיינזלץ].

Unlike sudden tragedies such as captivity, illness usually develops gradually. It is designed to act as a messenger from God, urging the individual to repent. Herein lies their greatest mistake. While wise and righteous people immediately examine their actions and correct their ways at the first sign of sickness, these individuals ignore the warnings. They fail to turn to God until their condition becomes unbearable, their bodies reject all food, and they find themselves at the very edge of death [רד״ק, מאירי].

This suffering ultimately serves as a tool for spiritual correction and the cleansing of past wrongs. It is particularly necessary for someone who mistakenly believes they are completely free of sin, much like the historical case of King Hezekiah. Sickness forces a person to confront their errors. Furthermore, this physical agony is a direct consequence of their earlier choices. Because these individuals did not willingly afflict themselves through fasting and sincere repentance while they were still healthy, God imposes this suffering upon them against their will, shaking them awake from their deep spiritual slumber [אלשיך].
