TSK · Numbers 35:12

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

Otherwise the blood avenger will chase after the killer in the heat of his anger, eventually overtake him, and kill him, though this is not a capital case since he did not hate him at the time of the accident.

Anyone who accidentally kills someone can escape there; these cities will be a place of asylum from the avenger of blood.

Now the entire family has risen up against your servant, saying,‘Turn over the one who struck down his brother, so that we can execute him and avenge the death of his brother whom he killed. In so doing we will also destroy the heir.’ They want to extinguish my remaining coal, leaving no one on the face of the earth to carry on the name of my husband.”
