'Unintentionally' in the Bible

that the manslayer who kills any person unintentionally, without premeditation, may flee there, and they shall become your refuge from the avenger of blood.

These were the appointed cities for all the sons of Israel and for the stranger who sojourns among them, that whoever kills any person unintentionally may flee there, and not die by the hand of the avenger of blood until he stands before the congregation.
