Numbers 35:26

The killer (manslayer) had to stay in a special city (called a "city of refuge") as a consequence for the death he had caused. He had to stay in a city of refuge until he or the high priest died. After the high priest's death, the manslayer could return home, and the avenger of blood could not take revenge.

Six of the Levites’ towns had a special purpose. They served as cities of refuge. A city of refuge was a place where a person could run for safety after accidentally killing someone.

These cities show the humanitarian (care for human life) side of Hebrew law (see also Deuteronomy 4:41–43; 19:1–13; Joshua 20).

These six towns offered protection when someone killed accidentally or unintentionally (compare Exodus 21:12–14).

The 48 towns given to the Levites were spread throughout Israel. In the same way, the six cities of refuge were placed in different parts of the land. This made them easy to reach for anyone who needed safety (see Joshua 20:7–8).

Before these cities were established, a person could sometimes seek safety by holding on to the altar. The altar was a place connected with worship (for example, 1 Kings 1:50–53; 2:28–34; compare Exodus 21:14).

Other ancient peoples also had places of refuge. Often these places were connected to an altar (see Exodus 21:12–14; 1 Kings 2:28–34). However, only ancient Israel created entire towns as places of safety. This practice shows Israel’s special concern for justice and the protection of human life.
