'Avenger of Blood' in the Bible

The avenger of blood shall himself put the murderer to death: when he meets him, he shall put him to death.

or in enmity struck him with his hand, so that he died; he who struck him shall surely be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meets him.

then the congregation shall judge between the striker and the avenger of blood according to these ordinances;

and the congregation shall deliver the manslayer out of the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, where he was fled: and he shall dwell therein until the death of the high priest, who was anointed with the holy oil.

and the avenger of blood find him outside of the border of his city of refuge, and the avenger of blood kill the manslayer; he shall not be guilty of blood,

lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and strike him mortally; whereas he was not worthy of death, inasmuch as he did not hate him in time past.

then the elders of his city shall send and bring him there, and deliver him into the hand of the avenger of blood, that he may die.

that the manslayer who kills any person accidentally or unintentionally may flee there. They shall be for you a refuge from the avenger of blood.

If the avenger of blood pursue after him, then they shall not deliver up the manslayer into his hand; because he struck his neighbor unintentionally, and did not hate him before.

These were the appointed cities for all the children of Israel, and for the stranger who sojourns among them, that whoever kills any person unintentionally might flee there, and not die by the hand of the avenger of blood, until he stands before the congregation.

Then she said, "Please let the king remember the LORD your God, that the avenger of blood destroy not any more, lest they destroy my son." He said, "As the LORD lives, not one hair of your son shall fall to the ground."
