In the future era of redemption, a profound and fundamental shift will transform the relationship between God and the people of Israel [ביאור שטיינזלץ, צאינה וראינה, אברבנאל]. The bond will deepen into a perfect, loving union, much like a marriage, as the nation completely leaves behind the sins of its past. Instead of relating to God as a distant master or owner, the people will approach Him with the affection, closeness, and devotion of a true partnership. The former dynamic, characterized by lordship, possession, and control, will be entirely abandoned [רש״י, מלבי״ם].
The primary approach among commentators explains this evolution based on the teachings of the Sages, noting that the relationship will elevate from the distant state of a bride still living in her father's house to the intimate reality of a bride who has moved into her new home with her husband. Consequently, the service of God will flow from pure love rather than fear. This new closeness will also change how God interacts with the world. Rather than guiding the nation from behind the scenes through the laws of nature, heavenly princes, or stars, God will watch over Israel face-to-face, without any intermediaries [מלבי״ם, אברבנאל]. God's direct communication with the nation emphasizes this close and personal relationship [מלבי״ם, אברבנאל].
Beyond the shift in the marital dynamic, the rejection of master-servant terminology serves another crucial purpose related to the eradication of idolatry. The old terms of lordship carry a double meaning, echoing the names of ancient idols. In the future, the people will find these associations so repulsive that they will feel ashamed to utter any word that even hints at the idolatrous practices of their past. God Himself will assist the nation in completing this process of repentance, ensuring that the remnants of these old names are entirely uprooted from their vocabulary [אבן עזרא, רד״ק, מצודת דוד, ביאור שטיינזלץ, אברבנאל].
