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 And if the Lord shall enlarge thy borders, as he sware to thy fathers, and the Lord shall give to thee all the land which he said he would give to thy fathers;

9 if thou shalt hearken to do all these commands, which I charge thee this day, to love the Lord thy God, to walk in all his ways continually; thou shalt add for thyself yet three cities to these three.

10 So innocent blood shall not be spilt in the land, which the Lord thy God gives thee to inherit, and there shall not be in thee one guilty of blood.

11 But if there should be in thee a man hating his neighbour, and he should lay wait for him, and rise up against him, and smite him, that he die, and he should flee to one of these cities,

12 then shall the elders of his city send, and take him thence, and they shall deliver him into the hands of the avengers of blood, and he shall die.
