Many things were by the law of Moses ordered to be done when they came to Canaan and this among the rest, the appointing of sanctuaries for the protecting of those that were guilty of casual murder, which was a privilege to all Israel, since no man could be sure but some time or other it might be his own case; and it was for the interest of the land that the blood of an innocent person, whose hand only was guilty but not his heart, should not be shed, no, not by the avenger of blood: of this law, which was so much for their advantage, God here reminds them, that they might remind themselves of the other laws he had given them, which concerned his honour. 1. Orders are given for the appointing of these cities (Jos 20:2), and very seasonably at this time when the land was newly surveyed, and so they were the better able to divide the coasts of it into three parts, as God had directed them, in order to the more convenient situation of these cities of refuge, Deu 19:3. Yet it is probable that it was not done till after the Levites had their portion assigned them in the next chapter, because the cities of refuge were all to be Levites' cities. As soon as ever God had given them cities of rest, he bade them appoint cities of refuge, to which none of them knew but they might be glad to escape. Thus God provided, not only for their ease at all times, but for their safety in times of danger, and such times we must expect and prepare for in this world. And it intimates what God's spiritual Israel have and shall have, in Christ and heaven, not only rest to repose themselves in, but refuge to secure themselves in. And we cannot think these cities of refuge would have been so often and so much spoken of in the law of Moses, and have had so much care taken about them (when the intention of them might have been effectually answered, as it is in our law, by authorizing the courts of judgment to protect and acquit the manslayer in all those cases wherein he was to have privilege of sanctuary), if they were not designed to typify the relief which the gospel provides for poor penitent sinners, and their protection from the curse of the law and the wrath of God, in our Lord Jesus, to whom believers flee for refuge (Heb 6:18), and in whom they are found (Phi 3:9) as in a sanctuary, where they are privileged from arrests, and there is now no condemnation to them, Rom 8:1. 2. Instructions are given for the using of these cities. The laws in this matter we had before, Num 35:10, etc., where they were opened at large. (1.) It is supposed that a man might possibly kill a person, it might be his own child or dearest friend, unawares and unwittingly (Jos 20:3), not only whom he hated not, but whom he truly loved beforetime (Jos 20:5); for the way of man is not in himself. What reason have we to thank God who has kept us both from slaying and from being slain by accident! In this case, it is supposed that the relations of the person slain would demand the life of the slayer, as a satisfaction to that ancient law that whoso sheds man's blood, by man shall his blood be shed. (2.) It is provided that if upon trial it appeared that the murder was done purely by accident, and not by design, either upon an old grudge or a sudden passion, then the slayer should be sheltered from the avenger of blood in any one of these cities, Jos 20:4-6. By this law he was entitled to a dwelling in that city, was taken into the care of the government of it, but was confined to it, as prisoner at large; only, if he survived the high priest, then, and not till then, he might return to his own city. And the Jews say, "If he died before the high priest in the city of his refuge and exile, and was buried there, yet, at the death of the high priest, his bones should be removed with respect to the place of his fathers' sepulchres."

Cities of refuge - An institution of this kind was essentially necessary wherever the patriarchal law relative to the right of redemption and the avenging of blood was in force; we have already seen that the nearest of kin to a deceased person had not only the right of redeeming an inheritance that had been forfeited or alienated, but had also authority to slay on the spot the person who had slain his relative. Now, as a man might casually kill another against whom he had no ill-will, and with whom he had no quarrel, and might have his life taken away by him who was called the avenger of blood, though he had not forfeited his life to the law; therefore these privileged cities were appointed, where the person might have protection till the cause had been fully heard by the magistrates, who certainly had authority to deliver him up to the avenger, if they found, on examination, that he was not entitled to this protection. On this subject see the notes on Num 35:11 to the end.

And if the avenger of blood pursue after him,.... To the city of refuge, whither he is fled, and demand him:

then they shall not deliver the slayer up into his hands; to be slain by him, but shall protect him:

because he smote his neighbour unwittingly, and hated him not beforetime; See Gill on Num 35:22; see Gill on Num 35:23, and See Gill on Deu 19:6.

he that doth flee unto one of those cities shall stand at the entering of the gate of the city--It was the place of public resort, and on arriving there he related his tale of distress to the elders, who were bound to give him shelter and the means of support, until the local authorities (Jos 20:6), having carefully investigated the case, should have pronounced the decision. If found guilty, the manslayer was surrendered to the blood-avenger; if extenuating circumstances appeared, he was to remain in the city of refuge, where he would be safe from the vindictive feelings of his pursuers; but he forfeited the privilege of immunity the moment he ventured beyond the walls.
