'Accidentally' 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.

And if the avenger of blood pursues him, they must not hand the one who committed manslaughter over to him, for he killed his neighbor accidentally and did not hate him beforehand.

These were the cities of refuge appointed for all the Israelites and for resident foreigners living among them. Anyone who accidentally killed someone could escape there and not be executed by the avenger of blood, at least until his case was reviewed by the assembly.
