Joshua 20

These were the cities appointed for all the children of Israel and for the stranger who dwelt among them, that whoever killed a person accidentally might flee there, and not die by the hand of the avenger of blood until he stood before the congregation. v.9

Read chapter 20
Now that the land is settled they are reminded to set up cities of refuge just as they did before.  These cities were for a man to flee and find shelter till his trail if he accidentally murdered someone.  The interesting thing I just picked up on is that these are already inhabited cities.  Theses are cities in someones tribe.  There are three appointed on one side of the Jordan River (where 2 1/2 tribes were) and three appointed the other side (where the other 8 1/2 tribes were), all conveniently placed so that all the tribes had one easier to get to than another.  All the cities were up upon mountains, that they might be a great distance from the avenger probably.  What's even more interesting is that all these cities are the priests cities.  The priests didn't have one land inheritance like the other tribes but were spread out and given land among all the tribes of Israel.  Matthew Poole's Commentary says the reason for this is:

partly that these causes might be more impartially examined and justly determined by them, who are presumed best able to understand the law of God, and most obliged and likely to follow it in their judgment, and not to be biassed by any affection or corrupt interest; and partly that their just reputation with the people, and their good counsels, might lay some restraint upon revengeful persons, who might be inclined or tempted to follow the man-slayer thither, and endeavour to kill him there.

Is there someone in your life you live with or near that you can go to for refuge in a matter that gives godly counsel as these Levites do?
