After a long period of suffering and subjugation, a firm divine promise arrives announcing the end of torment. The burden of punishment is shifting away from the Israelites and onto the nations of the world. God reveals Himself as taking direct control over His people's struggles, permanently removing the bitterness that accompanied them in exile. He declares Himself as the exclusive sovereign over Israel, establishing that from this point forward, He is their only master, replacing the foreign nations that previously ruled over them [רד״ק, צאינה וראינה]. God establishes His sovereignty with a twofold approach in His leadership: He shows mercy toward the Israelites, while directing harsh judgment toward the nations [אהבת יהונתן]. The primary approach among commentators is that God is personally taking up His people's cause, fighting on their behalf, and seeking justice against the nations that harmed them.
The central promise revolves around the imagery of a cup, which serves as a metaphor for the bitter troubles, harsh decrees, and long sufferings of exile [שטיינזלץ, צאינה וראינה]. God taking this cup away symbolizes that these hardships will never again afflict the people [מצודת דוד]. However, commentators offer different perspectives on the exact nature of this vessel and what remains inside it. One approach suggests the imagery refers to the bitter dregs settled at the bottom of a wine cup. Mentioning these dregs serves to reinforce the promise, ensuring that the end of their suffering is absolute [מצודת דוד, צאינה וראינה]. Another perspective views the imagery as describing a specific type of goblet. According to this idea, the Israelites drank and emptied their goblet, but the larger cup it was poured from remained full. God now removes the entire cup from their hands so they can never refill their goblet again [שד״ל]. A third, more complex interpretation divides the imagery into two distinct cups. The first is the cup of disaster and exile, which the Israelites have already consumed entirely, meaning God is now simply taking away the empty vessel. The second is a cup of wrath that still contains a bitter drink. God promises the Israelites that they will not have to drink its remnants, as these will be passed on to others [מלבי״ם].
On a deeper, allegorical level, these cups represent human desires and destructive impulses. The first cup hints at the urge for idol worship, which poisons and dulls a person's mind and heart. The second cup symbolizes the desire for immorality, which inflames and incites a person. God promises the Israelites that in the future, He will completely remove these destructive urges from them, ending their internal control. Meanwhile, the urge for idol worship will remain among the other nations of the world, preserving their free choice [אהבת יהונתן].
