'Avenger' in the Bible

The blood avenger himself will put the killer to death; he must put him to death when meeting him.

then the community will judge between the striker and between the blood avenger according to these ordinances.

The community will deliver the killer from the hand of the blood avenger, and the community will restore him to the city of his refuge to which he fled; and he will live there in it until the death of the high priest who was anointed with holy oil.

and the blood avenger finds him outside the territory of the city of his refuge, and the blood avenger kills the killer, {he will not be guilty of blood}

[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.

From the mouth of children and infants you have founded strength on account of your enemies, to silence [the] enemy and [the] avenger.

because of [the] voice of [the] taunter and [the] reviler, because of [the] enemy and [the] avenger.

O Yahweh our God, you answered them. You were a forgiving God to them, but an avenger of their [wrong] deeds.
