'Slayer' in the Bible

so that the person (manslayer) who kills any person unintentionally, without premeditation, may flee there, and they shall be your refuge from the blood avenger.

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.

He shall live in that city until he has stood before the congregation for judgment [and if acquitted of murder he must stay there], until the death of the one who is the high priest in those days. Then the offender (manslayer) shall return to his own city and his own house from which he fled.’”
