Joshua 20:3

That the slayer that killeth [any] person unawares [and] unwittingly may flee thither: and they shall be your refuge from the avenger of blood.

Ver. 3. That killeth any person unawares and unwittingly.] Not presumptuously, with a high hand, and of forethought malice; but either by chance medley, as they call it, or in his own necessary defence, when he must either kill or be killed, and he cannot avoid it. For that tenet of Soto is false, Defensio cum interfectione est licita, quia fuga est ignominiosa.
