'Killeth' in the Bible

then ye shall appoint you cities to be cities of refuge for you, that the manslayer that killeth any person unwittingly may flee thither.

For the children of Israel, and for the stranger and for the sojourner among them, shall these six cities be for refuge; that every one that killeth any person unwittingly may flee thither.

Whoso killeth any person, the murderer shall be slain at the mouth of witnesses: but one witness shall not testify against any person that he die.
