Joshua 20
1Then the LORD said to Joshua, 2“Tell the Israelites to designate the cities of refuge, as I instructed you through Moses, 3so that anyone who kills another unintentionally or accidentally may flee there. These will be your refuge from the avenger of blood. 4When someone flees to one of these cities, stands at the entrance of the city gate, and states his case before its elders, they are to bring him into the city and give him a place to live among them.
5Now if the avenger of blood pursues him, they must not surrender the manslayer into his hand, because that man killed his neighbor accidentally without prior malice. 6He is to stay in that city until he stands trial before the assembly and until the death of the high priest serving at that time. Then the manslayer may return to his own home in the city from which he fled.”
Perhaps not the usual encouragement or thanksgiving, but it is good to reflect that the basis of our system of laws is Biblical. The moral reasoning behind the Old Testament's civil and judicial laws can and should continue to inform how we govern ourselves today.
