The downfall of Edom unfolds against a backdrop of global redemption and joy, creating a sharp contrast between the bright fate of the world and the ultimate doom awaiting this specific nation. Commentators offer different perspectives on the exact nature and timing of this worldwide celebration.
One approach connects these events to the end of days. According to this view, the global joy takes place when the Kingdom of Heaven is fully revealed and God restores His kingdom on earth. At the exact moment the entire world experiences this profound happiness, Edom will be struck with total desolation ([רש״י] and [מצודת דוד]).
Another perspective shifts the focus to the Israelites returning to their homeland. In this scenario, the widespread joy occurs when the Israelites return to their inheritance and settle there in peace. For Edom, the punishment is twofold. First, they are forced to watch the happiness of the Israelites before experiencing their own collapse. Then, while the rest of the world celebrates this peaceful return, Edom is left to suffer in ruin and mourning ([מלבי״ם] and [ביאור שטיינזלץ]).
Ultimately, these events reflect a strict standard of measure for measure. Because Edom once celebrated the ruin of the Israelites' land, justice requires a mirrored response. In the future, the entire earth will celebrate the destruction and emptiness of Edom, matching the exact cruelty they once displayed ([רד״ק] and [מלבי״ם]).
