True repentance requires more than simply avoiding wrongdoing; it demands a proactive commitment to moral and social repair. God places this active pursuit of justice as a strict and necessary condition for the people. A genuine shift in direction means they must take concrete steps to fix their everyday behavior [שטיינזלץ]. This practical repair is achieved through the active execution of fairness and justice [שטיינזלץ] in all interactions between people [אברבנאל]. The focus rests heavily on fulfilling positive interpersonal duties, establishing that real change requires taking positive action.
This proactive demand serves as the foundation for the prophet's ongoing rebuke. By first establishing the duty to actively pursue justice, the groundwork is laid to then warn the people against severe violations, such as oppressing the weak, shedding blood, and engaging in idolatry. Ultimately, this strong moral requirement is meant to completely uproot a dangerous misconception. The people had fallen back into a pattern of sinning while relying on a false sense of security, wrongly believing that the mere physical presence of God's house would automatically protect them from disaster and shield them from His punishment [אברבנאל].
