'Avenger of Blood' in the Bible

The avenger of blood himself is to kill the murderer; when he finds him, he is to kill him.

or if in hostility he strikes him with his hand and he dies, the one who struck him must be put to death; he is a murderer. The avenger of blood is to kill the murderer when he finds him.

the assembly is to judge between the slayer and the avenger of blood according to these ordinances.

The assembly is to protect the one who kills someone from the hand of the avenger of blood. Then the assembly will return him to the city of refuge he fled to, and he must live there until the death of the high priest who was anointed with the holy oil.

and the avenger of blood finds him outside the border of his city of refuge and kills him, the avenger will not be guilty of bloodshed,
