Here is, 1. The nomination of the cities of refuge on that side Jordan where Israel now lay encamped. Three cities were appointed for that purpose, one in the lot of Reuben, another in that of Gad, and another in that of the half tribe of Manasseh, Deu 4:41-43. What Moses could do for that people while he was yet with them he did, to give example to the rulers who were settled that they might observe them the better when he was gone. 2. The introduction to another sermon that Moses preached to Israel, which we have in the following chapters. Probably it was preached the next sabbath day after, when the congregation attended to receive instruction. He had in general exhorted them to obedience in the former chapter; here he comes to repeat the law which they were to observe, for he demands a universal but not an implicit obedience. How can we do our duty if we do not know it? Here therefore he sets the law before them as the rule they were to work by, the way they were to walk in, sets it before them as the glass in which they were to see their natural face, that, looking into this perfect law of liberty, they might continue therein. These are the testimonies, the statutes, and the judgments, the moral, ceremonial, and judicial laws, which had been enacted before, when Israel had newly come out of Egypt, and were now repeated, on this side Jordan, Deu 4:44-46. The place where Moses gave them these laws in charge is here particularly described. (1.) It was over-against Beth-peor, an idol-temple of the Moabites, which perhaps Moses sometimes looked towards, with a particular caution to them against the infection of that and other such like dangerous places. (2.) It was upon their new conquests, in the very land which they had got out of the hands of Sihon and Og, and were now actually in possession of, Deu 4:47. Their present triumphs herein were a powerful argument for obedience.

That the slayer might flee thither,.... For refuge; the slayer of a man, but not any slayer, but

which should kill his neighbour unawares; by accident to him, without any design and intention to kill him; ignorantly, as the Septuagint version; and so Onkelos:

and hated him not in times past; it having never appeared that there had been a quarrel between them, and that the slayer had shown any enmity to the man slain any time before the fact, or bore a grudge against him, or spite unto him:

and that, fleeing unto one of these cities, he might live; in peace and safety unto his own death, or unto the death of the high priest, when he was released from his confinement to the city of his refuge, and might return to his tribe, house, family, and possessions.

Then Moses severed three cities on this side Jordan--(See on Jos 20:7).
