'Unintentionally' in the Bible

so that a person who kills someone unintentionally or accidentally may flee there. These will be your refuge from the avenger of blood.

If the blood avenger pursues him, they shall not hand the offender (manslayer) over to him, because he killed his neighbor unintentionally and without premeditation and did not hate him beforehand.

These are the cities appointed for all the Israelites and foreigners among them, so that anyone who kills a person unintentionally may flee there and not die at the hand of the avenger of blood until he stands before the assembly.
