XVII. (87) And it is worth while to examine with all the accuracy possible into some necessary points relating to this place. They are four in number. One, why it is that the cities which were set apart for the fugitives were not chosen out of those cities which the other tribes received as their portion, but only out of those which were assigned to the tribe of Levi. The second point is, why they were six in number, and neither more nor fewer. The third is, why three of them were beyond Jordan, and the other three in the land of the Canaanites. The fourth is, why the death of the high priest was appointed to the fugitives as a limit, after which they might return. (88) We must, therefore, say what is suitable on each of these heads, beginning with the first order. It is with exceeding propriety that the command is given to flee only to those cities which have been assigned to the tribe of Levi; for the Levites themselves are in a manner fugitives, inasmuch as they, for the sake of pleasing God, have left parents, and children, and brethren, and all their mortal relations. (89) Therefore the original leader of the company is represented as saying to his father and mother, "I have not seen you, and my brethren I do not know, and my sons I Disown,"[De 33:9.] in order to be able to serve the living God without allowing any opposite attraction to draw him away. But real flight is a deprivation of all that is nearest and dearest to man. And it introduces one fugitive to another, so as to make them forget what they have done by reason of the similarity of their actions. (90) Either, therefore, it is for this reason alone, or perhaps for this other also, that the Levitical tribe of the persons set apart for the service of the temple ran up, and at one onset slew those who had made a god of the golden calf, the pride of Egypt, killing all who had arrived at the age of puberty, being inflamed with righteous danger, combined with enthusiasm, and a certain heaven-sent inspiration: "And every one slew his brother, and his neighbour, and him that was nearest to Him."[Ex 32:26.] The body being the brother of the soul, and the irrational part the neighbour of the rational, and the uttered speech that which is nearest to the mind. (91) For by the following means alone can that which is most excellent within us become adapted for and inclined to the service of him who is the most excellent of all existing beings. In the first place, if a man be resolved into soul, the body, which is akin to it as a brother, being separated and cut off from it, and also all its insatiable desires; and in the second place when the soul has, as I have already said, cast off the irrational part, which is the neighbour of the rational part; for this, like a torrent, being divided into five channels, excites the impetuosity of the passions through all the external senses, as so many aqueducts. (92) Then, in regular order, the reason removes to a distance and separates the uttered speech which appeared to be the nearest to it of all things, in order that speech, according to the intention, might alone be left, free from the body, free from the entanglements of the outward senses, and free from all uttered speech; for when it is left in this manner existing in a solitary manner, it will embrace that which alone is to be embraced with purity, and in such a way that it cannot be drawn away. (93) In addition to what has been said above, we must also mention this point, that the tribe of Levi is the tribe of the ministers of the temple and of the priests, to whom the service and ministration of holy things is assigned; and they also perform sacred service who have committed unintentional homicide, since, according to Moses, "God gives into their Hands"[Ex 21:31.] those who have done things worthy of death, with a view to their execution. But it is the duty of the one body to know the good, and of the other body to chastise the wicked.
