'Kills' in the Bible

then you shall appoint you cities to be cities of refuge for you, that the manslayer who kills any person unwittingly may flee there.

For the children of Israel, and for the stranger and for the foreigner living among them, shall these six cities be for refuge; that everyone who kills any person unwittingly may flee there.

"'Whoever kills any person, the murderer shall be slain at the mouth of witnesses: but one witness shall not testify against any person that he die.
