The Israelite nation is portrayed through the stark and painful image of a battered, bleeding, and entirely neglected human body. Beneath this physical description lies a harsh rebuke of the people's spiritual and moral decay. The disasters brought upon them by their sins have left them shattered, yet these afflictions have failed to awaken them to repentance. The imagery of an affliction spreading completely from the bottom of the foot to the top of the head illustrates that not a single healthy or painless spot remains. Beyond the physical metaphor, commentators view this as a reflection of the nation's social structure. The corruption has infected every layer of society, beginning with the commoners and open sinners at the bottom, moving through the middle classes, and reaching all the way up to the leaders who cause the masses to stumble [תרגום יונתן, אהבת יהונתן]. Additionally, this total spread is interpreted as spanning the yearly calendar, from the pilgrimage festivals to the New Year, highlighting a cycle where the people sin, briefly contemplate repentance, and immediately revert to their corrupt ways [חומת אנך].
The physical injuries themselves are categorized into three distinct types: an open cut that tears the flesh and bleeds, an internal bruise where blood is trapped beneath the skin and changes color, and a fresh, weeping injury that continues to ooze fluids. The presence of all these injuries at once creates a picture of total medical helplessness. The required treatment for each injury contradicts the others. An open cut requires closing, a closed bruise must be softened and opened to drain the infection, and a wet, weeping injury needs to be dried. Because treating one wound would inevitably worsen another, the situation is rendered terminal and incurable [מלבי״ם].
Compounding this critical state is a complete lack of medical care. The primary approach among commentators is that essential healing actions have been entirely withheld from the stricken body. There is a difference of opinion regarding the first missing step of treatment. One approach explains that medicinal healing powders were not sprinkled over the injuries [רש״י, מצודת דוד], while another suggests that the infected fluids were never squeezed out [מלבי״ם, אבן עזרא, שד״ל]. Following this, the injuries were not wrapped in bandages to prevent them from spreading, nor were they soothed with oil to ease the pain. The shift in the description from plural actions to a singular focus occurs because while powders and bandages are applied over broad areas of the body, soothing oil must be carefully rubbed into each specific wound [רש״י].
On an allegorical level, this absence of medical intervention symbolizes the emotional numbness and stubbornness of the people. Despite enduring severe suffering and punishments from God, they refuse to take even the smallest step toward repentance to bring healing to their condition [רש״י, מצודת דוד, שד״ל]. Furthermore, this denial of a cure hints at the progressive stages of the nation's downfall, beginning with their refusal to heed warnings of doom, continuing through the destruction of their land, and culminating in the exile itself [חומת אנך].
