'Avenger' in the Bible

You will have the cities as a refuge from the avenger, so that the one who kills someone will not die until he stands trial before the assembly.

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,

Otherwise, the avenger of blood in the heat of his anger might pursue the one who committed manslaughter, overtake him because the distance is great, and strike him dead. Yet he did not deserve to die, since he did not previously hate his neighbor.

the elders of his city must send for him, take him from there, and hand him over to the avenger of blood and he will die.

so that a person who kills someone unintentionally or accidentally may flee there. These will be your refuge from the avenger of blood.

And if the avenger of blood pursues him, they must not hand the one who committed manslaughter over to him, for he killed his neighbor accidentally and did not hate him beforehand.

These are the cities appointed for all the Israelites and foreigners among them, so that anyone who kills a person unintentionally may flee there and not die at the hand of the avenger of blood until he stands before the assembly.

She replied, “Please, may the king invoke the Lord your God, so that the avenger of blood will not increase the loss, and they will not eliminate my son!”“As the Lord lives,” he vowed, “not a hair of your son will fall to the ground.”

Because of Your adversaries,You have established a strongholdfrom the mouths of children and nursing infantsto silence the enemy and the avenger.

because of the voice of the scorner and reviler,because of the enemy and avenger.
