6 lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and strike him mortally; whereas he was not worthy of death, inasmuch as he didn't hate him in time past.

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.
Lest the avenger of the blood pursue the slayer, while his heart is hot--This verse is a continuation of Deuteronomy 19:3 (for Deuteronomy 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" (Deuteronomy 19:10). In the case of premeditated murder (Deuteronomy 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 (Numbers 35:26-28; Joshua 20:6).
