יהושע, פרק כ׳, פסוק ט׳

The establishment of safe havens throughout the land ensures that justice is carried out fairly, preventing hasty acts of revenge in the wake of a tragedy. These locations provide an essential layer of protection for anyone who accidentally takes a life, guaranteeing them a proper legal process before any further action can be taken.

These cities are specifically designated and prepared well in advance to serve this exact protective purpose [רש״י, ביאור שטיינזלץ]. Beyond merely being prepared, they function as central gathering places. They act as the established locations where anyone involved in an accidental killing must assemble to find safety [מצודת ציון, רד״ק, מלבי״ם].

The right to seek refuge in these locations is granted equally to all the Israelites as well as to any foreigner living among them. There is absolutely no distinction made between a native citizen and a stranger when it comes to the fundamental right of saving a life and receiving equal legal protection [ביאור שטיינזלץ].

The primary goal of fleeing to these cities is to stop the victim's family, acting as the blood avenger, from taking immediate retaliatory action. The safe haven protects the individual until a formal trial can take place. The accused must stand before an official assembly for a proper legal hearing to determine if they are truly guilty of a capital offense. The city offers complete protection while the facts are being clarified. Only if the court officially rules that the person is guilty and liable for death is the avenger permitted to carry out the punishment [מצודת דוד, ביאור שטיינזלץ].
