'Avenger' in the Bible

And they must stand as your towns of refuge from the avenger in order that the killer may not die until he has stood trial before the community.

The avenger of blood himself must kill the murderer; when he meets him, he must kill him.

or with enmity he strikes him with his hand and he dies, the one who struck him must surely be put to death, for he is a murderer. The avenger of blood must kill the murderer when he meets him.

then the community must judge between the slayer and the avenger of blood according to these decisions.

The community must deliver the slayer out of the hand of the avenger of blood, and the community must restore him to the town of refuge to which he fled, and he must live there until the death of the high priest, who was anointed with the consecrated oil.

and the avenger of blood finds him outside the borders of the town of refuge, and the avenger of blood kills the slayer, he will not be guilty of blood,
