The bitter pain of abandonment and the long, lonely years of exile are ultimately replaced by a joyful reunion. The relationship between the Israelites and God is renewed, painted with the intimate image of a husband returning to his wife. The Creator of the world once again takes His people under His protection, displaying His absolute rule over all creation. When describing God's role in this relationship, terms of honor and majesty are used to convey a sense of complete unity, similar to the divine name itself [אבן עזרא, רד״ק, שד״ל]. These majestic descriptions reflect God's absolute lordship and ownership [מצודת ציון, אבן עזרא, שד״ל]. He is not only the one who created the nation, but the one who actively elevates them and makes them great [מצודת ציון].
The primary approach among commentators is that the Israelites were never truly considered a widow. The extended separation of the exile simply caused their deep bond to be forgotten, but God is destined to return and take the nation back to Him as a bride [שד״ל, ביאור שטיינזלץ]. During the long years of exile, the Israelites were controlled by foreign nations who acted as temporary masters. However, in the time to come, God, who was their original master and creator, will return to His rightful place as their true husband [רד״ק, צאינה וראינה].
God's identity as the commander of all heavenly and earthly armies highlights His absolute power to save the Israelites and restore their standing. Because He controls all forces above and below, no power can stand in His way or reverse His actions [מצודת דוד, רד״ק, מלבי״ם]. From another perspective, this mention of heavenly armies hints at the ministering angels. It reveals that the future redemption will take place with the full agreement and blessing of the heavenly court, free from any angelic jealousy or accusation [אהבת יהונתן]. Furthermore, God acts as a close, personal savior [ביאור שטיינזלץ]. Just as God is holy, the Israelites are destined to become holy as well, reaching a state where they will no longer sin [מלבי״ם].
While God's identity as the master of the heavenly armies has existed since the beginning of time, His future recognition as the God of the entire earth points to a new reality [מלבי״ם]. The primary approach among commentators is that in the time to come, all nations of the world will recognize God, turn to His teachings, and serve Him together [רד״ק, אבן עזרא, שד״ל]. This universal recognition also means that divine blessing and abundance will flow to the entire world directly from God Himself, completely independent of any intermediary forces or spiritual ministers [אהבת יהונתן].
