As, therefore, good men are the strongest part of cities, with a view to their duration, so also in that state of each individual of us, which consists of soul and body, the reasoning powers which are attached to prudence and knowledge, are the firmest part of its foundation; which the legislator, using metaphorical language, calls the ransom and the first-born, on account of those reasons which I have already mentioned.

In this way he also says, "The cities of the Levites are ransomed for ever, because the minister of God enjoys eternal freedom, according to the continuous revolutions of the ever-moving soul," and he admits incessant healing applications; for when he calls them ransomed, not once, but for ever, as he says, he means to convey such a meaning as this, that they are always in a state of revolution, and always in a state of freedom, the state of revolution being implanted in them because of their natural mortality, but their freedom coming to them because of their ministration to God.

But it is worth while to consider, in no passing manner, why he granted the cities of the Levites to fugitives, thinking it right that even these, who appear entirely impious, should dwell with the most holy of men. Now these fugitives are they who have committed, unintentionally, homicide. First of all, therefore, we must repeat what is consistent with what has been already said, that the good man is the ransom of the worthless one, so that they who have sinned will naturally come to those who have been hallowed, for the sake of being purified; and, in the second place, we must consider that the Levites admit the fugitives because they themselves are potentially fugitives;

for as they are driven away from their country, so these others also have left their children, their parents, their brethren, their nearest and dearest things, in order that they may receive an immortal inheritance instead of a mortal one. But they differ, because the flight of the one is involuntary, being caused by an unintentional action, but the flight of the others is voluntary, from a love of what is most excellent; and because the one have the Levites for a refuge; but the Levites have the Lord of all for their refuge, in order that those who are imperfect may have the sacred scriptures for their law; but that the others may have God for theirs, by whom they are hallowed.

Moreover, those who have committed unintentional homicide, have been allotted the same cities as the Levites to dwell in, because they also were thought worthy of a privilege because of a holy slaughter. When therefore the soul being changed, came to honour the Egyptian God, the body, as fine gold, then all the sacred writings rushing forth of their own accord with defensive weapons, namely demonstrations according to knowledge, putting forward as their leader and general the chief priest, and prophet, and friend of God, Moses, proclaimed an unceasing war in the cause of piety, and would not hear of peace till they had put down all the doctrines of those who opposed them, so that they naturally came to inhabit the same dwellings, inasmuch as they had done similar actions, though not the same.
