Deut 19:1-13

Laws concerning the Cities of Refuge 1When 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,2you shall set apart three cities in the land that the Lord your God is giving you to possess.3You shall calculate the distances 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.4Now this is the case of a homicide who might flee there and live, that is, someone who has killed another person unintentionally when the two had not been at enmity before:5Suppose someone goes into the forest with another to cut wood, and when one of them swings the ax to cut down a tree, the head slips from the handle and strikes the other person who then dies; the killer may flee to one of these cities and live.6But if the distance is too great, the avenger of blood in hot anger might pursue and overtake and put the killer to death, although a death sentence was not deserved, since the two had not been at enmity before.7Therefore I command you: You shall set apart three cities.8If the Lord your God enlarges your territory, as he swore to your ancestors—and he will give you all the land that he promised your ancestors to give you,9provided you diligently observe this entire commandment that I command you today, by loving the Lord your God and walking always in his ways—then you shall add three more cities to these three,10so that the blood of an innocent person may not be shed in the land that the Lord your God is giving you as an inheritance, thereby bringing bloodguilt upon you.11But if someone at enmity with another lies in wait and attacks and takes the life of that person, and flees into one of these cities,12then the elders of the killer's city shall send to have the culprit taken from there and handed over to the avenger of blood to be put to death.13Show no pity; you shall purge the guilt of innocent blood from Israel, so that it may go well with you.
