4. Here is the rule about a person who kills someone. That person can run to one of those cities for safety. The rule applies to all those who kill a neighbor they didn't hate and didn't mean to kill.
5. For example, suppose a man goes into a forest with his neighbor to cut wood. When he swings his ax to chop down a tree, the head of the ax flies off. And it hits his neighbor and kills him. Then that man can run to one of those cities and save his life.
6. If he doesn't go to one of those cities, the dead man's nearest male relative might become very angry. He might chase the man. If the city is too far away, he might catch him and kill him. But he isn't worthy of death, because he didn't hate his neighbor.
7. That's why I command you to set apart for yourselves three cities.
8. The Lord your God will increase the size of your territory. He took an oath and promised your fathers he would do it. He will give you the whole land he promised them.
9. But he'll do it only if you are careful to obey all of the laws I'm commanding you today. I'm commanding you to love the Lord your God. I want you to live always as he wants you to live. When he gives you additional land, you must set apart three more cities.
