2. Thou shalt separate three cities for thee in the midst of thy land—Goelism, or the duty of the nearest kinsmen to avenge the death of a slaughtered relative, being the customary law of that age (as it still is among the Arabs and other people of the East), Moses incorporated it in an improved form with his legislative code. For the protection of the unintentional homicide, he provided certain cities of refuge—three had been destined for this purpose on the east of Jordan (De 4:41; Nu 35:11); three were to be invested with the same privilege on the west of that river when Canaan should be conquered.

     3. Thou shalt prepare thee a way—The roads leading to them were to be kept in good condition and the brooks or rivers to be spanned by good bridges; the width of the roads was to be thirty-two cubits; and at all the crossroads signposts were to be erected with the words, Mekeleth, Mekeleth, "refuge, refuge," painted on them.

     6, 7. Lest the avenger of the blood pursue the slayer, while his heart is hot—This verse is a continuation of De 19:3 (for De 19:4, 5, which are explanatory, are in a parenthetical form), and the meaning is that if the kinsman of a person inadvertently killed should, under the impulse of sudden excitement and without inquiring into the circumstances, inflict summary vengeance on the homicide, however guiltless, the law tolerated such an act; it was to pass with impunity. But to prevent such precipitate measures, the cities of refuge were established for the reception of the homicide, that "innocent blood might not be shed in thy land" (De 19:10). In the case of premeditated murder (De 19:11, 12), they afforded no immunity; but, if it were only manslaughter, the moment the fugitive was within the gates, he found himself in a safe asylum (Nu 35:26-28; Jos 20:6).

     8, 9. And if the Lord thy God enlarge thy coast—Three additional sanctuaries were to be established in the event of their territory extending over the country from Hermon and Gilead to the Euphrates (see Ge 15:18; Ex 23:31). But it was obscurely hinted that this last provision would never be carried into effect, as the Israelites would not fulfil the conditions, namely, "that of keeping the commandments, to love the Lord, and walk ever in his ways." In point of fact, although that region was brought into subjection by David and Solomon, we do not find that cities of refuge were established; because those sovereigns only made the ancient inhabitants tributary, instead of sending a colony of Israelites to possess it. The privilege of sanctuary cities, however, was given only for Israelites; and besides, that conquered territory did not remain long under the power of the Hebrew kings.
