Betrayal of trust and cruel humiliation stand at the heart of this prophetic warning, which is directed at a leader or nation that weaponizes alcohol to degrade others. Under the guise of friendship, victims are plied with drink, but the intent is far from hospitable. The perpetrator targets peers, often fellow kings [רד״ק]. Instead of offering genuine hospitality, the host intentionally gathers toxic anger and poison, adding it to the drink [רש״י, מצודת ציון, רד״ק, ביאור שטיינזלץ], or deliberately brings out a wineskin to heavily intoxicate them [אבן עזרא, רד״ק]. Another perspective suggests the forced drinking is designed to physically heat the bodies of the victims [מלבי״ם].
Ultimately, the goal of this violent hospitality is to strip the victims of their dignity. Most commentators understand this as a deliberate plot to expose the victims' nakedness and subject them to public shame [רש״י, מצודת ציון, רד״ק, ביאור שטיינזלץ, אבן עזרא, אברבנאל]. Alternatively, the humiliation is achieved by bringing the drinkers to such a profound state of intoxication that they publicly vomit [מלבי״ם].
The identity of this cruel host is debated, with interpretations ranging from specific historical figures to broad national allegories. The primary approach identifies the perpetrator as Nebuchadnezzar, the king of Babylon. He would gather the foreign kings he held captive and force them to drink from his poisoned cup purely to mock them, degrade them, and revel in their disgrace [רד״ק, ביאור שטיינזלץ, אבן עזרא]. Some suggest his cruelty extended even further, using this intoxication to sexually exploit his captives [רש״י].
Another historical interpretation connects this betrayal to the feast of Belshazzar, who forced his officers to drink from the sacred vessels of the Temple. Consequently, they became intoxicated, absorbed the wrath of God, fell into an eternal stupor, and were slaughtered that very night by the invading Persian and Median armies [רש״י, מלבי״ם]. However, this reading is strongly disputed by those who argue that it is entirely inappropriate to attribute a desire to gaze upon nakedness and shame to God [אבן עזרא].
Beyond individual monarchs, the prophecy serves as a powerful national allegory for betrayal. Some identify the treacherous figure as the entire Babylonian nation. Initially, Babylon allied with Israel through love and friendship, but eventually turned against them. Driven by a burning hatred, Babylon forced Israel to drink a poisoned cup, seeking not only to conquer their land but to witness their downfall [מצודת דוד]. Similarly, others apply this prophecy to the Roman Empire. Rome maintained a peace treaty with Israel for twenty-six years before ultimately betraying them, destroying them, and forcing them to drink from a cup of poison to expose their utter disgrace to the world [אברבנאל].
