'Kills' in the Bible

You are to set aside six towns of refuge from the towns that you will be giving to the descendants of Levi, where someone who kills a human being may run for shelter. In addition, give them 42 other towns.

they are to designate some towns of refuge so that anyone who kills someone inadvertently may flee there.

that is, places of refuge for the Israelis, the resident alien, and any travelers among them. Anyone who kills a person inadvertently may flee there."

and the blood avenger finds him outside the town of refuge where he had fled and kills him, the blood avenger is not to be found guilty of murder.
