4. As it was, the involuntary manslayer had thus to undergo a considerable penalty. Having to reside in the city of refuge, he could no longer cultivate his farm or follow his ordinary avocations; he must have found the means of living in some new employment as best he could. His friendships, his whole associations in life, were changed; perhaps he was even separated from his family. To us all this appears a harder line than justice would have prescribed. But, on the one hand, it was a necessary testimony to the strong, though somewhat unreasonable feeling respecting the awfulness, through whatever cause, of shedding innocent blood. A man had to accept of this quietly, just as many a man has to accept the consequences--the social outlawry, it may be, and other penalties--of having had a father of bad character, or of having been present in the company of wicked men when some evil deed was done by them. Then, on the other hand, the fact that the involuntary destruction of life was sure, even at the best, to be followed by such consequences, was fitted to make men very careful. They would naturally endeavour to the utmost to guard against an act that might land them in such a situation; and thus the ordinary operations of daily life would be rendered more secure. And perhaps it was in this way that the whole appointment secured its end. Some laws are never broken. And here may be the explanation of the fact that the cities of refuge were not much used. In all Bible history we do not meet with a single instance; but this might indicate, not the non-existence of the institution, but the indirect success of the provision, which, though framed to cure, operated by preventing. It made men careful, and thus in silence checked the evil more effectually than if it had often been put in execution.
