'Unwittingly' in the Bible

And this is the case of the slayer who shall flee thither that he may live: he that smiteth his neighbour unwittingly, whom he hated not previously;

that the slayer who unwittingly without intent smiteth any one mortally may flee thither: and they shall be your refuge from the avenger of blood.

And if the avenger of blood pursue after him, they shall not deliver the slayer up into his hand; for he smote his neighbour unwittingly, and hated him not previously.
