Then the Lord said to Moses:  “Speak to the Israelites and say to them: 'When you cross the Jordan into Canaan,  select some towns to be your cities of refuge, to which a person who has killed someone accidentally may flee.  12 They will be places of refuge from the avenger, so that anyone accused of murder may not die before they stand trial before the assembly
All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance, admitting that they were foreigners and strangers on earth.  People who say such things show that they are looking for a country of their own.  If they had been thinking of the country they had left, they would have had opportunity to return.  16 Instead, they were longing for a better country—a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared a city for them.
