Divine justice and the distribution of reward and punishment in the world operate much like the pouring of a cup of wine. Through this imagery, God administers His judgment, giving every individual and nation exactly what they deserve while reversing the fortunes of the righteous and the wicked. The cup held in God's hand serves as a powerful symbol of His providence and judgment. The primary approach among commentators is that this represents a cup of disaster, poison, and punishment designed to confuse the minds of the wicked [רש״י, מצודת דוד, המאירי]. Conversely, an alternative perspective views this cup as a symbol of the continuous goodness, blessing, and kindness that God constantly pours into the world [מלבי״ם].
The liquid inside the cup is subject to various interpretations. It is described as a strong, fine, and bubbling wine [רש״י, מצודת ציון, מלבי״ם], or as a red wine, a color that represents the attribute of strict justice [רד״ק, אלשיך, המאירי]. Others describe it as a fermenting, burning liquid [ביאור שטיינזלץ] or as cloudy and muddy [אבן עזרא]. This wine is fully mixed, which can mean it is blended with spices and drugs [ביאור שטיינזלץ] or simply prepared as a standard mixed wine [רד״ק, מצודת ציון]. On a deeper conceptual level, this mixture represents the careful blending of strict, harsh justice with the soothing waters of mercy [אלשיך].
As God pours from the cup [רש״י, מצודת ציון], it is so full that the wine spills over the edges [רד״ק, אבן עזרא]. This pouring is constant and unceasing, yet the cup miraculously remains full of blessing [מלבי״ם]. The way the drink is distributed explains the dramatic shifts in history and human destiny. While the Israelites drank from the cup of suffering during their exile, in the future, the wine will be poured out toward the other nations and the wicked [רד״ק, המאירי]. When looking at the suffering of the righteous, the wine that spills from the top portion of the cup represents hardships that are tempered with mercy, ultimately intended for their long-term good [אלשיך].
The fate of the wicked, however, is entirely different. They do not receive the carefully mixed wine; instead, they are forced to drink the bitter sediment and waste at the very bottom of the cup [מצודת ציון]. They will drain, suck, and squeeze the cup completely dry [מצודת ציון, ביאור שטיינזלץ]. These dregs symbolize the heavy, unyielding attribute of strict justice without a single drop of mercy, a punishment reserved for the wicked after they have exhausted any merits they may have had in this world [אלשיך]. The severity of the punishment directly matches the level of their wrongdoing. Those who are only partially wicked drink the cloudy wine near the top, while the entirely wicked are left to consume the dregs [אבן עזרא]. Ultimately, the wicked bring this punishment upon themselves. While God pours out good wine and blessing, the wicked fail to prepare themselves to receive His goodness, and their poor choices leave them consuming the harmful sediment [מלבי״ם].
