The exclusive bond between God and the Israelites defines the very reason for the nation's existence. They are meant to serve as a living witness to God's actions, broadcasting His greatness to the world. God formed this specific nation to belong to Him entirely [אבן עזרא, שד״ל, ביאור שטיינזלץ]. This exclusive relationship is the fundamental reason for their creation [רש״י, מצודת דוד, צאינה וראינה]. In fact, the Israelites are viewed as the primary focus of all creation [אברבנאל]. Their very existence makes it possible for God to reveal His divine traits to the world. Qualities such as mercy, grace, and kingship cannot exist in a vacuum; they require a people to receive them, just as a king cannot rule without a nation [אהבת יהונתן]. This deep care is a direct extension of God's ongoing commitment to sustain and provide for His chosen people [שד״ל].
The ultimate destiny of the Israelites is to actively publicize the miracles and wonders God performs for them. This applies especially to the great miracle of their redemption from exile and their return to their homeland [רד״ק, אבן עזרא, צאינה וראינה]. It is not enough for the people to simply harbor respect for God in their hearts. They are expected to recognize the direct benefits they receive from His actions and speak about them openly [מלבי״ם].
Understanding this core mission also sets the stage for a firm rebuke. God makes it clear that future miracles and the ultimate rescue from exile will not occur because later generations will have earned them through good deeds. The people will not necessarily deserve to be saved. Instead, God will bring about the redemption strictly for His own sake. He will save them to ensure that the original purpose of their creation—to declare His praise—is finally and fully realized [רד״ק, צאינה וראינה].
