במדבר, פרק ל״ה, פסוק כ״ט

After detailing the complex procedures for handling both intentional and unintentional killers, the legal discussion concludes by establishing a permanent institutional framework. The rules governing the killer form an absolute statute of justice that must be respected, even in eras when courts lack the practical authority to carry out capital punishment [ביאור שטיינזלץ, העמק דבר].

The reach of this judicial system extends far beyond its immediate borders. The requirement to hold court sessions applies not only within the Land of Israel but also in the lands of the exile [רלב״ג, מלבי״ם, צפנת פענח, הכתב והקבלה]. The primary approach among commentators is that a court judging capital cases can indeed operate outside the Land of Israel, yet its authority remains entirely dependent on the active existence of the supreme court sitting in the Temple chamber in Jerusalem [רש״י, רש״ר הירש, שפתי חכמים, גור אריה]. Furthermore, judges outside the Land of Israel were only permitted to judge because they operated under the formal ordination received from the sages within the Land [רש״ר הירש, מזרחי].

While the legal system spans across different regions, practical distinctions remain. Within the Land of Israel, there is an obligation to appoint judges in every single city. Outside the Land, however, courts are only established in central districts [תורה תמימה, גור אריה]. Additionally, while the judges themselves hold authority abroad, the actual cities of refuge function exclusively within the Land of Israel [תורה תמימה].

The requirement that this justice system must continue throughout all generations presents a historical challenge. Capital cases ceased even before the Temple was destroyed, as they require the active presence of the altar and the High Priest in Jerusalem. How, then, can this be viewed as a continuing obligation, especially in exile? To resolve this, many explain that the command does not refer strictly to capital cases. Instead, it establishes an eternal duty for the people to maintain a functioning judicial body. Even after the Temple's destruction, there remains a constant obligation to set up courts to judge monetary cases, fines, and injuries [רמב״ן, רבנו בחיי, תורה תמימה]. In this framework, modern judges act as the legal agents of those formally ordained judges from the past [מזרחי]. Alternatively, others suggest that the requirement for all generations does not demand absolute eternity. Rather, it refers to a limited period lasting several generations, specifically applying only as long as the Temple remained standing [גור אריה].
