There was no place of safety for the guilty murderer, not even the altar of Yahweh. Thus all superstitious notions connected with the right of sanctuary were excluded. Adonijah and Joab 1 Kings 1:50; 1 Kings 2:28 appear to have vainly trusted that the common feeling would protect them, if they took hold of the horns of the altar on which atonement with blood was made Leviticus 4:7. But for one who killed a man "at unawares," that is, without intending to do it, the law afterward appointed places of refuge, Numbers 35:6-34; Deuteronomy 4:41-43; Deuteronomy 19:2-10; Joshua 20:2-9. It is very probable that there was some provision answering to the cities of refuge, that may have been based upon old usage, in the camp in the Wilderness.

I will appoint thee a place whither he shall flee - From the earliest times the nearest akin had a right to revenge the murder of his relation, and as this right was universally acknowledged, no law was ever made on the subject; but as this might be abused, and a person who had killed another accidentally, having had no previous malice against him, might be put to death by the avenger of blood, as the nearest kinsman was termed, therefore God provided the cities of refuge to which the accidental manslayer might flee till the affair was inquired into, and settled by the civil magistrate.

And if a man lie not in wait,.... For the life of another to take it away; or does not do it willingly, as the Septuagint version, does not seek after it, nor design it:

but God delivers him into his hand; it being suffered and ordered by the providence of God, without whose knowledge and will nothing comes to pass, even what may seem to be a contingent thing, or matter of chance, to us; or it is so brought about in providence, that one man falls into the hands of another, and his life is taken away by him, though not purposely and maliciously; because, as Aben Ezra expresses it, for another sin which he has committed, and for which he must die in this way, though not intended by the person the more immediate cause of his death:

then I will appoint thee a place whither he shall flee; and there be safe both from the avenger of blood, and the civil magistrate; which place, while Israel were in the wilderness, was the camp of the Levites, according to Jarchi, or the altar, as follows; but when they were come to Canaan's land, there were cities of refuge appointed for such persons, that killed a man unawares, to flee to, and where they were safe from private vengeance, and falling a sacrifice to public justice.

And if a man lie not in wait, but {l} God deliver him into his hand; then I will appoint thee a place whither he shall flee.

(l) Though a man be killed unawares, yet it is God's providence that it should so be.

21:12-21 God, who by his providence gives and maintains life, by his law protects it. A wilful murderer shall be taken even from God's altar. But God provided cities of refuge to protect those whose unhappiness it was, and not their fault, to cause the death of another; for such as by accident, when a man is doing a lawful act, without intent of hurt, happens to kill another. Let children hear the sentence of God's word upon the ungrateful and disobedient; and remember that God will certainly requite it, if they have ever cursed their parents, even in their hearts, or have lifted up their hands against them, except they repent, and flee for refuge to the Saviour. And let parents hence learn to be very careful in training up their children, setting them a good example, especially in the government of their passions, and in praying for them; taking heed not to provoke them to wrath. Through poverty the Israelites sometimes sold themselves or their children; magistrates sold some persons for their crimes, and creditors were in some cases allowed to sell their debtors who could not pay. But man-stealing, the object of which is to force another into slavery, is ranked in the New Testament with the greatest crimes. Care is here taken, that satisfaction be made for hurt done to a person, though death do not follow. The gospel teaches masters to forbear, and to moderate threatenings, Eph 6:9, considering with Job, What shall I do, when God riseth up? Job 31:13,14.
