Deuteronomy 19:10 Meaning and Commentary

Deuteronomy 19:10

That innocent blood be not shed
As it would be if such a slayer as before described was killed by the avenger of blood, before he could get to one of these cities of refuge, or supposing that they had not bean appointed, or a sufficient number of them:

which the Lord thy God giveth thee for an inheritance;
to be enjoyed by them and their children after them, provided they did not defile it by their sins, but observed the commands of the Lord to obey them and

so blood be upon thee;
the guilt of innocent blood crying for vengeance, as would be the case if such a man's blood was shed as before described; it seems as if the guilt would rather affect the whole land, for not having a proper provision of "asylums" for such persons, than the avenger of blood.

Deuteronomy 19:10 In-Context

9 Carefully obey all these laws I'm giving you today. Love the Lord your God, and always do what he wants you to do. Then the Lord your God will enlarge your land as he promised your ancestors, giving you the whole land he promised to them. After that, choose three more cities of safety
10 so that innocent people will not be killed in your land, the land that the Lord your God is giving you as your own. By doing this you will not be guilty of allowing the death of innocent people.
11 But if a person hates his neighbor and, after hiding and waiting, attacks and kills him and then runs to one of these cities for safety,
12 the older leaders of his own city should send for the murderer. They should bring the person back from the city of safety and hand him over to the relative who has the duty of punishing the murderer.
