19 When the Lord your God has cut off the nations whose land the Lord your God is giving you, and you have dispossessed them and settled in their towns and in their houses, ² you shall set apart three cities in the land that the Lord your God is giving you to possess. ³ You shall calculate the distances^[a] and divide into three regions the land that the Lord your God gives you as a possession, so that any homicide can flee to one of them.
