A profound divine promise establishes a perfect mirror image between past devastation and future revival for the people of Israel and Judah [ביאור שטיינזלץ]. God declares that the very same power, focus, and attention He previously directed toward punishing the nation will now be channeled entirely into their restoration.
The primary approach among commentators is that God's involvement is characterized by intense speed, persistence, and dedicated effort [מצודת ציון, רד״ק]. Just as God previously hurried and exerted great effort to bring tragedy upon the people, He will now act with that exact same level of swiftness and dedication to bring them goodness [מצודת דוד, ביאור שטיינזלץ].
The sheer intensity of the past devastation is illustrated through actions of total ruin: uprooting, breaking apart, and tearing down [מצודת ציון, ביאור שטיינזלץ]. Yet, in direct contrast to this sequence of absolute destruction, the divine message shifts to an opposing promise. God assures the people that He will apply His relentless dedication toward building them up and establishing them anew [מצודת ציון].
