'Avenger of Blood' in the Bible

[He does this] lest the avenger of blood might pursue after the killer, because {he is hot with anger} and he overtakes him, because it is a long distance [to the city of refuge], and [so] {he kills him}, but {he did not deserve a death sentence}, because he [was] not hating him {before}.

then the elders of his city shall send and take him from there, and they shall give him into the hand of the avenger of blood, and he shall be put to death.

Anyone who kills a person by accident or unintentionally may flee there; they will be for yourselves a refuge from the avenger of blood.

And if the avenger of blood pursues after him, they will not hand over the killer into his hand, because he killed his neighbor unintentionally, and {he did not hate him previously}.

These were the cities designated for all the {Israelites}, and for the foreigners dwelling among them, for anyone that kills a person unintentionally to flee there, and not die by the hand of the avenger of blood, {until there is a trial} before the congregation.
