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

8 "If ADONAI your God expands your territory, as he swore to your ancestors that he would, and gives you all the land he promised to give to your ancestors -

9 provided you keep and observe all these mitzvot I am giving you today, loving ADONAI your God and always following his ways - then you are to add three more cities for yourselves, besides these three;

10 so that innocent blood will not be shed in the land ADONAI your God is giving you as an inheritance, and thus blood guilt be on you.

11 "However, if someone hates his fellow member of the community, lies in wait for him, attacks him, strikes him a death blow, and then flees into one of these cities;

12 then the leaders of his own town are to send and bring him back from there and hand him over to the next-of-kin avenger, to be put to death.
