19:1-13 Here is the law settled between the blood of the murdered, and the blood of the murderer; provision is made, that the cities of refuge should be a protection, so that a man should not die for that as a crime, which was not his willing act. In Christ, the Lord our Righteousness, refuge is provided for those who by faith flee unto him. But there is no refuge in Jesus Christ for presumptuous sinners, who go on still in their trespasses. Those who flee to Christ from their sins, shall be safe in him, but not those who expect to be sheltered by him in their sins.Lest the avenger of blood pursue the slayer,.... These words are to be connected with Deuteronomy 19:3, where it is ordered to prepare the way to the cities of refuge, and to divide the land into three parts, for the convenience of the slayer to flee thither, lest he that was next of kin, and incensed against the slayer, and determined to avenge what was done, should pursue after him:

while his heart is hot; by reason of the loss of his relation, upon which his passions being raised, his heart becomes inflamed with wrath and anger; which pushes him upon an eager and hasty pursuit of the slayer, before he sits down and coolly considers and deliberates on the affair:

and overtake him, because the way is long, and slay him; wherefore it was proper that everything should be done to make the way to these cities as easy and as short as it could be:

whereas he was not worthy of death; had not committed an action deserving of it, it being done ignorantly and without notice, as follows:

inasmuch as he hated him not in time past; See Gill on Deuteronomy 19:4.
