'Kills' in the Bible

These six cities shall be for refuge for the sons of Israel, and for the alien and for the sojourner among them; that anyone who kills a person unintentionally may flee there.

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

‘If anyone kills a person, the murderer shall be put to death at the evidence of witnesses, but no person shall be put to death on the testimony of one witness.
